Of course BRUNSWICK is the best because i have 4 Brunswick balls it does work for me but one thing my fave Rhino RE (Brunswick) has crack up which broke my heart so have 3 Brunswick and one hammer for 10 Pin.
Columbia simply because my fav ball is part of their range. Havent purchased anything new recently, dont need to yet (still enough reaction from my old gear). My highest games have been on my oldest less agressive gear, that says something to me, more people should be looking in the cupboards than spending $400 on a new ball
