I used to ride the floater and had a blast on it. Honestly though if your new board has rocker you aren't really going to gain anything. The recommendation to demo real powder boards is a good one though.
Well the Floater has been sitting on the wall for years since I have been riding my burton twin for the last 7 years. I think the floater i got in 99. IT was time for a new board and thats why I picked up the SMokin superpark the other day, still using the same P1 bindings though that I picked up about 5 years ago.
I will probably just rent a powder board like you said. Thanks guys......
