watch the 604 alt if you are not heavy and/or powerful....it still catches me with too much foam in serious sections sometimes...thats at 90kg+...the planshape and rocker do a great job here...a moderate volume will go a long way....if i wanted to tear up on it, i would have 6'0...to make it a bit easier i would have a 6'2...i got the 6'4 for when i was 95+ and wanted to give my back an easy ride...if i hammer it, it still goes nuts though..!!!
