Mumzie,
I have not yet found one place to summarize all or even most of the drilling info. In fact, some manufacturer's drilling info is even contradictory; so, it is obvious no one site can posisbly give what you're asking for.
Marios's is good as are several ball manufacturers: Storm, Columbia, Brunswick (very good), Ebonite, Morich.
Bowling This Month used to be Excellent, but what I've learned (if it's of any value to anyone else) is a distillation of reading BTM since 1996, talking to good drillers here (such as T-God, King of the Mill, Constantine, and the like), learning from my driller, drilling balls in different ways, and 453 other sources. Sorry, can't help.
