Would have loved to learn from Uncle Homer, rest his soul.
Today, current pros, Edwin Evers, Shin Fukae.
I like both of these guys for their techniques, Shin would be great teaching Japanese finesse techniques, Edwin, a lot of the other stuff.
I think I'd be numb if it were KVD. He's so good, so fast, I don't know how much I could learn, in one day, LOL.
