Gravity Shift 30x4x60, pin under, 2000 ab, hand shined. Good on heavy, med_heavy shots. Has been a killer in my PBAX summer league. On Scorpion I averaged 211 for 12 games. Can't wait to see what it does on Shark. Usually allows me to throw my normal ball speed(17+) on the higher volume shots. Only drawback is the cover isn't as tunable as my Shift or Spit Fire. I either like it at 2000 shined or 4000 shined or it hits and rolls terrible.
Shift 45x4.5x60, pin under, 1500, shined on a spinner. Love the predictability of how it rolls. Great for medium shots and when the lanes open up. My favorite Storm ball. Very tunable cover. Have liked it dull or shined anywhere between 1000 and 2000 depending on the condition. Won 2 tournaments throwing it last season.
Spit Fire, 4" pin to PAP, pin over ring, X-hole on PAP, 4000 ab shined on a spinner. Good for medium if there's backend or on the lighter stuff. Love how it rolls. Very tunable cover. Have had it everywhere between 1000 - 4000 and liked it. Definitely works better shined. Had an excellent look at the Iowa Open(US Open shot) with it(2000 shined) but spare shooting(usually a strength) cost me the finals - FIBJAM - 190 avg. w/13 opens the last 5 games(8 total).
I can't see replacing my Shift or Spit Fire anytime soon but could see a Fast(based on riggs review) replacing the Spit Fire and maybe a HyRoad or Virtual Energy replacing the Shift some day.
I will say I do like the way most Storm balls clear the front of the lane and how tunable their covers are. That's why most of my arsenal is Storm.
