Personally I dont think there is that much difference between high BB and low BB. When I first got my GU it was DIFFERENT but not bad, all you have to do is adjust your technique a bit. I could happily ride my old Kenny Belaey or my GU, just so happens the GU is bomb proof, which is a bonus for me. And to make Ali C happy, I got my GU when Tunni was on a low BB zoo and Damon was on his KOT, so had nothing to do with my decision Bear in mind if you do go high BB and new bar/stem combo will be REQUIRED. I'm running a HI-Fi stem with zoo bars if that helps. My 2 cents
