After weeks of trying them and coming super close, today I finally got several pretty lengthy fakie ollie to fakie 5-0s (or switch fs nose grind, if you prefer) to pop-out mid ledge.
I was feeling so psyched after that I also managed to learn 360 pop shoves.
One of the better skate days I've had lately, and I never even left the park, which just goes to show I should talk less shit on parks...
