I will be attending a Doce Pares seminar soon (although I train in Tae Kwon Do and boxing), I have been told its a good oppurtunity that shouldnt be missed as the instructor is 10th dan Danny Guba

. I was a bit skeptical at first as i usually am of anyone over 6th dan but from doing a bit of research it is clear he is no phony. I was wondering if anyone has any experience with Doce Pares or has trained with Danny Guba, any info would be much appreciated.
Thanx in advance
