I'm using 25 back and front. I find 30 too hard to get any bounce, but saying that sometimes i feel that 25 is also too hard :P
But yeah, 25 back and rear :D am gonna keep at that for a while :lol:
edit: im 11 and a bit stone if that makes any difference
edit again: Including my old one, iv only ever seen 3 white zebbers
