With regards to which company dominates....that's more like an issue of what style of clothing is the coolest. I doubt most of the serious bowlers who score pick one company because they're "The Best", but because they get a certain "Look" from the equipment they love.
I've used Columbia, Track, Lane 1, Ebonite, but I prefer AZO and Visionary to those because of the HIT and CARRY these balls produce. I can get the same reaction out of throwing a beach ball down the lane if I tried hard enough.
