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.

Just a bum looking like a pro!
This is a quick review of the Pro-Motion. This ball is as advertised, smooth and continuous. I am a player that tends to have a sharp reaction off of the spot and this ball truly just rounds out the shape and continues on the backend. This is my first run with the SPEC coverstock and it has resisted lane shining to date.

A second one with a stronger layout is going to join my bag. Why? Where I bowl as a crazy puddle in the middle that forces you in and makes it hard for the ball to slow down but the dry is CRAZY by the middle of game two.

Weight: 16#
Surface: OOB
Layout: Pin over the ring finger

Great down and in ball!
A very powerful and consistent ball to play up the boards. A lot of energy as it drives through the deck. Great ball especially for strokers!
