concurring with all of the 5-0 talk, especially backside. matter of fact, back fifties are a lot harder on ledges than crooked grinds also. I've have a massive fear of the slipout forever but the backside ones are even scarier now that I've got a bad wrist - having to catch myself falling forward is a nightmare.
backside roll-ins and backside slashes for hang-up reasons
switch front shuvs for absolutely no reason
and pivot fakies - every single new ramp I try it on, regardless of size it's like getting myself to do it for the very first time again. I KNOW I can do it but just can't get myself to fakie manny for a third of a second back down the ramp.
