From watching Pete and Sy cut, I'd also propose that you're possibly moving the fader long distances and that smaller movements will help speed you up.
I thought you scratched reverse at first because the fader spent so much time on the other side
When I drop the sound I always have a habbit or puling the fader to the other band to cut out the beat. That's a bad habbit. I do it too often
haha i've been working on doing this intentionally I used to do it with one type of scratch, but i've been working on incorperating it into thoer techniques and you get a cool cutting effect on the beat along with the cuts, but theyre offbeat to each other so it soinda really choppy when its right
