I've been looking at a few balls. I found goods deals on the following. Fear Factor, x factor, triple xfactor, triple xtreme, and x factor ace. I bowl about 17-19 mph, med revs, and would probably rate as a tweener. Oil is med to med heavy. Depends if on league or house. Any suggestions of what ball and what drilling pattern to use. I like a lot of hook. Any help would be appreciated. Thanks,
