Last knife work I did with him was with standard rubber trainers, so i don't know what he's got going on with these double-ended things. I'm sure it's cool stuff though, and I'm looking forward to seeing what the other instructors bring back from the seminar.
Yes, he's very much a stand up, no bullshit guy, who also happens to be extremely laid back and approachable. The little bit of AMOK! philosophy that I've picked up from your posts is very much in line with Latosa Escrima concepts.
