The Swag Unknown is one of those pieces you know is strong the moment it leaves your hand. This ball is built for traction, and it shows it early. On a typical house shot, the Unknown read the midlane aggressively and made a hard, defined move that punished any shot that drifted into friction too soon. If you weren’t in the oil, you paid for it — and that’s exactly what this ball is designed to do. Where the Unknown shines is in heavier volume environments. Give it oil and it becomes a powerful, predictable option that blends the pattern and creates a heavy, continuous motion through the pins. It’s not a skid flip ball and it’s not meant to be. This is a benchmark style piece with teeth, ideal for bowlers who need a ball that won’t miss the midlane and won’t skate past the breakpoint on fresh. For speed dominant players, bowlers who see sport or challenge patterns, or anyone who needs a reliable read on higher volume conditions, the Unknown fits that role perfectly. On lighter or cliffed house shots, it may simply be too much unless you’re comfortable moving in and creating angle.

THE STORM PHASE 2 SOLID FINALLY HAS SOME COMPETITION FROM SWAG! I FEEL THIS NEW UNKNOWN SOLID IS WHERE THE UNREAL WAS INTENDED TO BE. BOTH THE UNREAL AND UNKNOWN HAVE VERY SIMILAR CORE NUMBERS BUT DIFFERENT COVER STOCKS. THE UNREAL IS THE NEVER QUIT AND THE UNKNOWN MYSTERY BOTH WITH THE NEW ADDITIVE FROM SWAG THE AP26.THE UNKNOWN SEEMS TO READ THE LANES MUCH EARLIER AND A MORE CONTINUIOUS MOTION. THE COLORS ARE BEAUTIFUL, TRUE BLUE AND STEEL BLUE LOOK GREAT GOING DOWNLANE AND NOTICALBLE MAKING THE TRANSITION DOWN LANE. THIS IS A TRUE BENKMARK BALL ALLOWING YOU TO HAVE A GREAT IDEA WITH WHAT LANE CONDITIONS ARE GIVING YOU. I WOULD RECOMMEND THIS BALL TO ANY STYLE OF BOWLER. THE UNKNOWN IS AVAILABLE SEPTEMBER 7TH. MAKE SURE THAT YOU PICK YOU UP ONE!

The Unknown is easily my favorite SWAG release to date. What stands out to me most is the combination of incredible strength and controllability. This ball is so forgiving its like a heatseaking missile set on the pocket. The Unknown gives me excellent traction through the midlane while still saving enough energy to create a smooth, crushing motion on the backend. The biggest advantage for me is how predictable this ball is. Shot after shot, I feel like I know exactly what the ball is going to do. The Unknown has a strong but controlled shape that makes it extremely versatile. It reads the midlane hard enough to handle heavier oil, but the backend motion is smooth and powerful rather than flippy. When it gets to the pins, it carries that energy through the pocket with authority. For my game, the Unknown is a dependable piece that I can rely on when I need strength, control, and predictable ball motion.

The SWAG Unknown Bowling Ball is the first ball out of my bag on fresh oil every league night. For reference, my ball layout is 70 x 4 x 20. I am a medium speed, low to medium rev bowler. This ball is great for when I know I am going to be dealing with heavy oil or if I’m dealing with longer oil patterns. It gets through the fronts easily and stores up enough energy to continue through the pins without burning up. This ball has a predictable motion that continues through the pins. Not only does this ball do its job, it looks good going down the lanes as well. I would definitely recommend this ball if you’re looking for a solid benchmark ball.

My first session was on a fresh league pattern. Right away, the Unknown Solid did exactly what it’s supposed to do: it read the midlane. Dressed in the subtle True Blue/Steel Blue swirls, it’s not flashy, and neither is the motion. It is smooth. It is honest. There is absolutely no "surprise" snap at the breakpoint. It gave me a very strong, arcing motion that started rolling about 35 feet down the lane and just continued through the pins. When I missed inside into the oil, it held line rather than skating. When I missed outside to the friction too early, it smoothed out the hook rather than jerking left violently. Being to play a tight line around second arrow (board 10) out to about board 7 at the breakpoint. I didn’t have to chase the oil inside too quickly because the symmetric core kept the ball from burning up too fast. The hit is soft but powerful; it has a tendency to carry light hits very well. As the fronts started to dry out and people migrated inside, the Unknown Solid started to struggle. The solid cover stock at 3000 grit began to read too early, causing the ball to lose its finish. I could make a small move inside, but the symmetric core didn't quite have the backend "pop" needed to return from deeper angles once the oil was gone. This is where I would typically transition to something like a shiny pearl or a hybrid with a lower RG. It’s not a ball that will "wow" you with Messenger strikes or catastrophic backend motion. But if you want a ball that you can trust to get you through the first game and a half of league with a consistent, readable look, this is it. It’s the "scout" that tells you exactly how the lanes are playing so you know when to switch to your more aggressive equipment.

Good afternoon everyone. Ron Steigerwalt here. I was a able to throw this ball. This ball is a absolute monster. This ball has the all brand new mystery solid AP26 cover stock. It comes out of the box with a 3000 grit finish. My layout is 45 x 4 1/4 x 30. I played straight with this ball and I was also able to open up the lane with this ball. I was bowling on 46ft house shot, and this ball comes off the spot hard, and it is very continuous threw the pin deck. This ball needs oil. Please visit my YouTube channel for my entire ball review at @Stinger10pin This ball is a must have in every bowlers arsenal. So please hurry up and yours today before they are all out of stock.

The Swag Unknown has been a ball that I’ve really enjoyed throwing. I drilled mine 25 × 4 × 45 using my PAP of 5 3/8 over and 7/8 up, and so far I really like the reaction I’m seeing. For my game, the Unknown gives me a good amount of length through the front of the lane while still making a strong, controlled move when it gets to the breakpoint. What stands out to me the most is how comfortable I feel throwing it. I don’t feel like I have to force the ball to make it back to the pocket. I can move around as the lanes change and still get a reaction I can trust. It’s one of those balls that gives me confidence when I step on the approach, and I can definitely see myself keeping the Unknown in my regular rotation.

Style: traditional 1 handed righty Rev rate: 450 Speed: 17 mph Layout: 55x3-3/4x35 I honestly didn't know what to expect with this ball at first. I watched a couple of ball reviews and read some. One thing that stood out to me was the fact that everyone kept talking about the "continuation" on this ball. Looking at the videos, the unknown was very controlled and carried well even when you opened up your angles. After throwing this ball a bit, I realized that the carry was better than what I'm used to with the other Swag balls, especially when I'm playing wide with this ball. One of my friends who was watching me throw this ball mentioned how it continuous it was through the pins despite opening up my angles so much. Threw this once in league with one of the games being a 279! I threw so many bad shots in that game, but I also had a lot of messengers and forgiveness from this ball when the horrible shots happened. I'm honestly super happy I got this ball and would easily recommend this ball to anyone who was looking for a ball that is easy controllable and has good continuation through the pins. Don't hesitate when deciding if you want to get this ball or not. I promise, you will not regret getting this one at all. You're welcome.

The SWAG Unknown is an impressive ball that offers a great combination of versatility, control, and hitting power. The AP26 cover with this new core is a deadly combination. Its a sanded, symmetric solid, the ball has a strong, predictable motion that makes it easy to read the lanes and adjust your line. It smoothly transitions off the breakpoint without that checkmark, while still providing plenty of energy through the pins. The Unknown has been reliable on a variety of lane conditions and gives me confidence when I need a consistent reaction. Have thrown this on typical house shot as well as sport shot and will say the reaction is the same, its just smooth and controllable. If you need something in your arsenal that is predictable, smooth and overall quite a bit of hook this is the ball for you.
