The Power Groove line has been a tremendous success for Brunswick. Designed primarily for bowlers buying their first performance ball, the Power Groove line delivers a tremendous amount of hook potential for the money.
The Power Groove Dry/R Green/Chrome is designed for a different type of bowler and lane condition.
Less traction in the oil, a smoother reaction off the dry and a lower hook potential than the shiny Power Groove reactive balls, the Power Groove DryR delivers a better match-up on dry lane conditions.
High RPM players will find the Power Groove Dry/R to be the tamest of Brunswick's reactive coverstock balls, making it an excellent ball to go to on dry lane conditions.
Low speed players who struggle to get the ball down the lane will find the Power Groove Dry/R creates more length, saving its hooking action for the back-end where it belongs.
Coverstock: The Green/Chrome Pearl features PowerBoost Dry, a tamer version of the PowerBoost reactive coverstock found on balls in the BVP line .
Core: The Power Groove DryR Green/Chrome uses Brunswick's DISC (Differential Increasing Side Cylinders) core technology which provides:
The largest track flare potential of any ball in its class.
Consistent track flare potentials at all weights from 12-16 pounds.
Larger, more consistent pin-out distances at all weights from 12-16 pounds.
A more driller friendly design. The precise geometric placement of high density side cylinders maximizes the increase in Track Flare Potential while maintaining symmetry for easy drilling.
Your Power Groove Dry/R Green/Chrome Pearl can be drilled using the standard drilling techniques developed for two-piece balls. Since the Power Groove Dry/R is intended for drier lane conditions Brunswick recommends using pin positions between 4 ?" to 5 ?", avoiding the most aggressive 3 3/8" (leverage) pin position. See the included drilling instructions for reaction characteristics and layout details.
Your Power Groove Dry/R Green/Chrome Pearl is finished with a high gloss surface which enhances its appearance and reduces hooking action in the oil. High gloss finishes can sometimes cause over/under reactions, too little hooking action in the oil, then too much hooking action off the dry, which can be hard to control. To increase hooking action and smooth out the ball reaction dull the surface, first with a fine 800-1000 grit abrasive. If more hooking action and a smoother reaction is desired dull the surface of the ball with a coarse 320-400 grit abrasive.
