Just kidding, the board isn't for sale!
But at 90 kegs I wouldn't worry about knee paddling. Looks cool when the lightweights do it, but us guys around 90ish are a little bit top heavy. Plus it means you have to go a bit wider and a bit thicker than you really need once you are surfing.
Stick with the 9'1. But try and sniff out a cheap Redline. They are a good blend between old and new.

And to any other lurkers out there, just log-in and start talking crap with the rest of us!
