I purchased these and they fit perfectly the only thing they don't have is the new no laces tightening system but for the sale price they won't disappoint you in the least bit. However if you only plan on bowling a few times a year they're not what you want I bowl pretty much as much as I can about 5 times a week.
Well i thought I was getting a ball that was valued higher than the Mystery ball price. But instead the ball i received i found at a lower price point than the Mystery ball amount. Disappointed but not hating.
Hi Antonio - I'm sorry to hear that. Please message us directly using our chat feature so we can get more details and try to work towards a solution.
Picked this one up cheap since C300 is no more. HK22C2 Pearl with a pretty big asym core in a beautiful ball. Yes please! Love the colors. The Rose Gold has gold metallic looking flakes that really catch the light and the purple pops. Haven't drilled it yet. Will update review once I've rolled it a bit.
Good ball cleaner and leaves the ball tacky.
Decent ball cleaner, it does the job but ive used better products.
The Track Theorem Pearl certainly catches your eye. The shelf appeal is outstanding, and Track did a great job with the colors and overall appearance of the ball.
That said, the reaction just didn’t quite hit the mark—no pun intended—based on what I was expecting from a pearl version of the Theorem line. I was hoping for a cleaner, more responsive shape that would complement the original, but the motion never really stood out or gave me the look I anticipated.
That’s not to say it’s a bad ball. It simply didn’t create the separation in reaction that I expected, especially considering how much I enjoyed other balls in the series. I found myself reaching for other options more often when I needed length and backend motion.
Every bowler matches up differently, but for me, the Theorem Pearl looked better on the shelf than it did on the lanes. It just didn’t live up to the expectations I had for a pearlized follow-up to one of my favorite releases.
The Track Paragon Shadow has been one of the most dependable strong balls I’ve owned. For a ball that reads the lane early and handles volume well, it does an impressive job of getting down the lane without burning up or rolling out.
What really stands out is how well it blends the pattern. On lower-friction house shots, this ball became one of my go-to options because it provided plenty of traction while still maintaining continuation through the pins. The motion is strong and smooth without being lazy, making it easy to trust when the lanes are tight or when carrydown starts to appear.
This ball has also bailed me out more than once in tournament competition, especially on modified house shots where control is just as important as total hook. Whenever I needed something that would read the lane reliably and keep me out of trouble, the Paragon Shadow was usually the answer.
If you’re looking for a strong asymmetrical ball that combines early read with surprisingly good downlane motion, the Paragon Shadow deserves a serious look. It has been one of the most reliable tournament pieces I’ve had in the bag.
The Track Theorem Solid has been one of the most underrated releases of the year in my opinion. It never seemed to get the attention that some of the bigger-name releases received, but based on performance alone, it absolutely deserved to be in the Ball of the Year conversation.
What I like most about this ball is the balance in its motion. It’s strong enough to handle fresh conditions and heavier volumes, but it never feels overly early or sluggish. The reaction is smooth and predictable, yet it still has enough kick downlane to drive through the pins and create excellent continuation.
That combination of strength and versatility makes it easy to trust. I can use it as a benchmark-type piece or as a step down from stronger asymmetrics, and it always seems to blend the lane well without sacrificing hitting power.
If you appreciate balls that are smooth, readable, and versatile rather than overly angular, don’t overlook this one. For me, the Theorem Solid has been one of the best and most underrated releases of the year.
Newly Released last Month, Another strong ball, haven’t drilled it yet. Great Addition Thanks BW, Nothing Hits Like a Hammer
I got a HK22C solid ball for a great deal!!!
Customer service reached out regarding the issue of my delivery. I'll update my review once I receive my ball.
Love this cleaner...just make sure if you're trying to order the refill package that it is the refill package and not the bottle...great cleaner tho
I bought two of these for my second time. Always an experience when opening the package and never disappointed.
