Steven,
You are corret in that I couldn't possibly test every ball I own or have own to its end. I did however throw a lot of Brunsick and Columbia bowling balls on different conditions and drillings. I tried a couple of Roto Grips, Dynothanes, Storm, Lanemasters, AZO as well as a few others, but I tested many Brunswick and Columbia bowling balls before deciding to throw Lane 1.
Columbia has worked well for some bolwers, but Columbia has been in financial trouble (might not be the right word but it will work) for some time now. They threw out some garbage of remakes, old cores, old coverstocks and a blend of coverstocks. They had not kept up with the R&D and used old stuff at todays prices.
Also they had difficulty at the factory with weightblock placement in the cores. You could ost times get the ball legal, but becaue of the weightblock placement you couldn't get the reaction from the ball that was touted or expected.
Now this is just my opinion and I welcome others. But this is bowling ball website for information, conversation and opinions.
