Doug,
I really think this refers to the type of conditions prevalent in your local bowling area. Whereas, I agree with your initial selection of balls, I tend to think the Bully, Oracle, Ultimate Inferno, and XXX will be the most talked about pieces for 2004-2005. In our area the UI reigns supreme, followed closely by the Killer Instincts, as far as useage and hitting power go. I've heard great stuff about those Diesels, though. The Rule, II, and FAZ could be super-sleepers, too.
