As the weak are eliminated, an EPIC BATTLE rages on! Roto Grip has forged the most effective weapon for the battlefield and puts it in the palm of your hand.
Roto Grip's "PRO PIN" technology is taking layouts and ball reaction to the extreme. Once only used on the Professional Tour for condition specific drillings, these balls are now being made available in limited quantities to the general bowling public.
Since the breakthrough of fine tuning reaction characteristics by the use of mass bias placements in the 1990's, large pin out balls have been a staple for many ROTO GRIP Pro Staffers on the professional tours. Big pin outs occur when the weight block tips to one side of the ball. The further the weight block is tipped, the more the mass is biased to one side of the ball pulling the CG away from the pin. Advantages of these balls are as follows:
-Enhanced dynamics
-Stronger preferred spin axis
-More drilling versatility
-Superior reaction characteristics
-USED ALMOST EXCLUSIVELY ON THE PROFESSIONAL BOWLING TOUR....
-Enables drillers to use larger extra holes increasing flare potential and ball reaction
