Switch stuff.
Has baffled me for years, but I'm finally getting some pop out of my switch ollies. Can now switch ollie small benches and shit, do some switch ledge tricks (switch tailslides, switch 5050s), etc.
I guess I'm finally seeing that there's no real magic trick to switch skating - it's just like learning to write with your wrong hand: all it takes is doing it over and over and eventually it'll start to seem natural. Sure took awhile for me, tho.
