In MT and BJJ, we'd roll and spar so much that this is never an issue, however, when I was training longfist, and when I was in college with a small group of guys training "traditional Japanese Karate" we did do this. In the karate class, I fought a guy who was a marine and came in saying that due to his military training, he could beat the pants off of any "karate guy".
In longfist, we once had a guy who came in, said he was a thai boxer and that he loved leg kicking. it was a sparring night anyway, so sifu put him against me. normally, we rotate partners, but he was stuck with me all night...
i'm nobody...i'm nobody. i'm a tramp, a bum, a hobo... a boxcar and a jug of wine... but i'm a straight razor if you get to close to me.
