I would consult with Galen Gentry at Legends for that "tweaking" of your ball's reaction; quite often, you can achieve what you want with a coverstock adjustment OR and cover adjustment and a properly located & sized balance hole. Be prepared to provide him with details on the ball (layout & cover finish), your style (PAP, ball speed, etc) and the conditions that you're rolling on ... the more info that you can provide, the better he'll be able to assist you.
If you email him with as much of that info (plus your phone number for him to call you back)and then call him about it, he can look at that email and have the info right in front of him as he speaks with you.
Contact info is:
galen@lanemasters.com and 1-888-526-3645 (they open a 8 AM Pacific time); if he's not there or unavailable, leave a voice mail and your contact info.
Good luck !!!
