For me its the straight kick to the knee area,seems like the fastest way to cripple an opponent .I'm surprise these guys don't practice it 10,000 times a day. Which is it for you?
face farts are totally underrated, just one good wiff and you opponent skillset has been reduced by half.
Very few MMA fighter can throw a good jab, only a few trainers teach their guys how to jab..... GSP has a pretty decent jab by MMA standards, but he worked with Roach quite a bit.
