I'd love to see that essay on training with wood without it cracking.
Concerning hubud, it is part of the training in DBMA. As a matter of fact I was training one of my private students in it rather heavily just this morning.
Concerning some of the negative commentary about it and similar training methods, see the thread "Tippy Tappy Drills-- thread or menace?" on this forum.
Of couse Guro Inosanto would be the best course of action for learning hubud! (And of course, I second Gruhn's kind words about our "Kali Tudo"(c) DVD
)
Training hubud is great fun and in my opinion when connected with the proper understandings can be of tremendous fighting value. If I may offer a suggestion-- learn it on your complementary side first (your left side if you are a righty) and ingrain it well, then learn it on your dominant side, then learn to fluidly flow between the two.
