It's you not the board. Oh NOEZ I CANTZ BUTTAHZ! Seriously the SL isn't that stiff I rode a cambered, a r.c., and other variations and I never had an issue and I'm 5lbs more than you. People need to realize it's not the stick that lets them butter its knowing how to manipulate the board. In this day and age you'll rarely find a board you can't do what you want with.
you're probably right about "its you, not the board" but i'm wondering how true that is with 10 year old boards. my custom from 2000 is way too stiff to butter imo....its also very hard to pop a decent ollie. truly cannot wait for next season and a new board......anyone else riding on a 10 year old board?
