I threw a Rival 'demo' ball for a few games today. Apparently, Columbia is getting seed test balls w/Switch Grips into select proshops. It's a good move for Columbia to get their new stuff in the hands of bowlers and build 'mindset' again. I know in my case, I wouldn't give them a second thought without some motivation.
Anyway, a very impressive piece of equipment. It revs up nice and smooth with good backend. I was surprised how aggressive it was given the shinny cover. My sense it that it will be versatile across most conditions except extremes.
I'm more of a Lane#1 guy, but this ball is the real deal. I'm tempted to pick one up when they become generally available in a few weeks.
