So I couldn't figure out why every time I tried to do a kickflip it turned into a 180 double kickflip, so I took a slow motion video and I discovered that what is happening is that my index finger is not doing the flip, it's bypassed, and it's the middle finger that scoops the board. Because the index finger misses the scoop, the board is allowed to rise up so it's vertical when my middle finger hits it, and so it spins and rotates into 180.

Great. Now I know what's going wrong. BUT I cant fix it even though I'm trying to scoop flat and low! Any tips how to properly scoop the board?

Thanks!
