PRO-MOTION

To create this very special PRO-Motion, Jason teamed up Storm’s Research and Development department to create a weight block design that is unique and benefits bowlers of all styles. It is a dynamic symmetrical piece that has some very unique characteristics. For bowlers looking to roll their best scores, the PRO-Motion gives total performance from foul line to head pin with a ball motion akin to the pros'.

The engine of change

The Piston core brings with it months of testing and validation in conjunction with the best player of our time: Jason Belmonte. Developed specifically for his line, the Piston Core creates separate helical archs that make the shape corkscrew as it tumbles. You can see the channels on the sides of the Piston Core and the large band through the equator which displaces the mass in a very specific way.



BREAKTHROUGH BEGINS

SPEC stands for “Storm Performance Enhanced Coverstock”. The intent behind this formula was to create something that withstands the rigors every bowling ball endures each time it takes a trip down the lane; namely, the friction and oil it encounters. We all know and accept that bowling balls smooth out over time, just like the tread on the tires of your car. With SPEC, you can expect consistent performance that is as tireless as it is dynamic. It’s bold, definite, and extremely potent.

Great ball, but poorly-matched with SPEC.
The ball itself exceeded my expectations. It gets through the fronts quick, revs up nicely, and tapers out evenly on the backend. It's helped me numerous times on my local house's custom-designed wet-dry house shot. But to be fair, I don't think SPEC Solid was a good coverstock choice. SPEC is just too slow for me. The Crux Prime was good with SPEC, but not this one. The coverstock and weight core simply do not get together well. Honestly, they should've used TX-16 from the Phaze II.

I love the ball so much!!!
reason because I bowl left handed two handed and when I throw it towards the second through third arrow I like how it reads the high part of the lane. Also, smooth reaction towards the exit point and it’s easy for me to control and to be consistent with it. Thank you STORM and Jason Belmonte for making this ball so awesome and fun to use.

Smooth
The Pro Motion is the perfect benchmark ball. Easy to read, smooth in the mid lane with a continuous arc down lane. Ideal for playing the lanes straighter
