I'm a long time Jiujitsu pracitioner and Pro MMA fighter. I was recently propositioned by a TKD academy to start and instruct a Jiujitsu program in their facilty. I've known the owner/head coach for a while and have no personal problems, however he comes from that old school TMA mentality(I'd tear your nuts off if you tried that ground wizardry on me, train of thought) and wants me to run my jitz class in a traditional style(yessir no sir, Bowing to get on the mats, charging for belt tests). Which I actually have no problem with. Just wondering if anyone here has any experience training/instructing grappling alongside a TMA program. I'm currently a student of his TKD program, which I really like. Just wondering about any possible friction from this setup.
