Alright I gotta ask this, cause every damned snowshop around here with people that consider themselves "expert riders" keep telling me my boards height is fine.. This guy I just got off on the phone was telling me how if I'm gonna be riding mammoth I don't want anything below a 155 because I'm gonna start sinking in. They all asked me where the board came up to my neck while on the phone, which is a red flag from what I've read.
I'm 5'11", weigh 152 and I ride a 159 Attack Banana, is it really too big for an all mtn board in Mammoth? My shoe size is a 9. Whats the ideal size for a do it all board?
