i'd go with the ride. they make solid boards. and also i'd lean toward a 158-160cm if your agressive. my wife at 5'5" 125# rides a 154 short board, 156 all around, and a 160 in the powder. i'm 5'11" 165# on a 160 when i teach, and a 165 to freeride. enjoy and get west when you can. there are plenty of couches in colorado to crash on.
