i currently ride a 7'2 x 22 x 3 merrick mbb. im 6'3 250 lbs. i was at a local shop today and they had a 6'9 x 20 1/2 x 2 7/8 arakawa shape, really nice. i was wondering if that would be to small for me? also its a fish style tail, how will that perform in small mush, as well as a little bigger stuff like up to 5 feet. please help.
