it is great. i wish i had time to do more. i don't study all of the disciplines all of the time.gracie jiujitsu is awsome, but i don't study it enough. i am really into the kali, as i fell it is a complete art,ie;weapons,hand 2 hand, cqc,and ground work. my instructor is an instructor under dan inosanto, so i am getting some of the best training around. i get to study kali and muay thai 3 times a week and i do my iron skills at home on a 6 day a week basis. i use the dog bros. dvds' on a daily basis also, "kkk" is the best for me. i have learned soooo much. we routinly refernce dog bros. in class.
