ElongatedStick can confirm. I was able to take a private lesson with Leal and the dude’s insane. The only other person who has wowed my like that has been Ausdemore.
I was wondering about the middle finger. I know it's frowned upon to an extent, but I also noticed in the 2016 cam, he had the same middle finger. I've always thought that the middle finger aids in downstroke control, but is there a reason for the way they're doing it?
