so damn close! you'll get it :) it's definitely not an easy trick, but once you get it once you'll have it unlocked!
I always try to hang the toes of my front foot slightly off the board, then kick my heel upwards and on an angle out into the heel-side pocket of the board myself.
You'll get it sooner than later though :) you're putting in the work!
Thanks man! I'm gonna focus on half cabs and ollies for a bit, try to get that height up and get super comfy on the board. It's just so damn rainy in Manchester! I wish i could skate everywhere but it's always wet!
