... I'm 265lb
and have heaps of fun on the Airush Cypher 5'10. It suprizingly handles choppy 20 knots water too.
Biggest complaint though, it needs deckpads as wax doesn't last long. With the 5 fin boxes, you got options, I can change the feel of the board with either tri or quad, and with each option, you can move the fins fore/aft making it even more options in feel.
I haven't tried the other boards so I don't know how good they are but this one is a lovely board for us heavier dudes.
