Wow! All these 6'+, large-ish 220+ fellows! Now I really feel like a lard ass!!
So you know that you aren't likely to bust a board that big,.. I started riding 3 seasons ago at 6 ft. around 195-200lbs on a 163cm board. I've since gained about 35-40 lbs. and may have shrunk a half inch due to my own back trouble.
So at easily 255-260lbs, fully geared up, I've been riding a Rome 159 and NeverSummer 157. I'm WAY outta the weight range of those and I manage OK!
...of course I ain't taking them off 40ft kickers or hitting the halfpipe either!
Oh, and I'm old
too! Hahaha! Have fun!
