fully focus on the end of the rail after the 2 on, then drop the toe and turn back the other way. you got it good but your not getting enough "preload" in you shoulders to pop it back around
u kinda go to big to get onto it, like u have 2 much air w ur first 270 that u have no time for the second one, id say either move ur rail back a foot or 2 or dont jump as high to get on, but u def got that trick.
