dont wanna be that guy who tells people how to do tricks BUUUUTTTTT...
an older dude told me as a grom that if you imagine you are skating within a square you can figure out where you board is gonna land-
front shuv/ Variel heel, fs bigspin ect - start in the bottom right corner (if your regs, left if your goofy) as you pop jump to the diaginal opposite corner youll be on the board every time.
pop shuv/ varial kickflip etc - start at bottom left (right for goofy) and jump to the opposite corner (top right)
this totally worked for me and unlocked a bunch of tricks.
the other tip i picked up was for straight kickflip you wanna drag your flicking toe through the truck bolt on the heel side of your deck and off the nose pocket, they ping up to your back foot every time.
now if anyone wants to shed some light on nollie tres id appreciate it, those fuckers have eluded me for a good ten years
