low bb is good for: taps gaps (well, holding on to them when landing) roll downs bunnyhops manuals 2 wheel balance High bb is good for: hooks back wheel control possibly sidehops Personally I think +6 makes a bike feel like a pogo stick, it makes it hard to hold onto moves when you land, loops out too easily in gaps. However, a low bb +1-2 is harder on the back wheel and can feel a bit slugish. I think you would get on really well with a +3 - 4 high bb
