I have to agree with IVAn when it comes to the arts of KARATE, I would take BJJ, wrestling, shoot fighting, and MUY TAI KB over the KATAS. Yes it si a beautiful art form but not too many people are going to stand there and watch you throw a round house. 90% of fights lead to the ground and if you cannot battle on the ground..then lights out. Watch UFC 1 and it will tell you right fromthe first fight.
The KOREAN was 12 years TAI KWON DOE and 10 KENPO. HIs oppent was 7 years BJJ, boxing, and college wrestling...well, the wrestler took the 3 punches as he shot in and is was over in the matter of 30 seconds.
No offense to those who have studied KARATE...it teaches dicipline, hand eye cordination, balance, strength, focus, and all that stuff. I just feel that 9 times out of 10 the grappler will win
