I have a Power Groove Proactive Black Sparkle in my rack that's waiting to be drilled with a 2"-to-PAP setup, had no time for the pro shop yet.
With a polished surface I expect this thing to be a good special purpose piece for slick lane surfaces and carrydown - but since it is a rather rolly setup (hence the choice of a high RG core), I do not expect the ball (or sucha setup in general) to be a good choice on dry lanes. Conquering wet/dry conditions with a stable reaction and predictable roll is its main purpose. It lacks length you need for dry /high friction lanes.
I'd rather increase the pin to PAP distance to at least 5", depending on your game, and put the pin under the fingers top avoid a flippy reaction. Pin-in balls with a low TW are a good basis, an entry level ball is recommended if you want to conquer dry to light conditions, as well as a shiny surface for added length.
Good luck, though, tough job to find a dry lane solution that actually works!
