i learned fs/bs noseblunts & fakie noseblunts on a concrete quarter pipe a couple weeks ago & had them on lock ever since somehow. everytime i tried those before i couldn't even get into them, for some reason that day i learned them all within 30 minutes. great day.
also i did my first switch 360 flip ever yesterday, best feeling ever. hoping i'll be able to do those comfortably too.
