Maybe wrong forum, but no one seems to be complaining...
I trained 9 years in traditional Okinawan Goju Ryu: 5 years in America and 4 in Japan, member of the I.O.G.K.F. under Morio Higaonna, who is in my estimation (and many others) the greatest living traditional martial artist.
After earning nidan in Japan I decided to try MMA and joined a shooto dojo to focus on grappling. I think my Goju Ryu training probably advanced me by 1-2 years in the ground game. As I'm sure you know, Go Ju = Hard Soft, which I think is an essential philosophy of sub grappling. Breathing, Relaxing, Flowing, and Exploding in a movement, feeling your opponent rather than seeing your opponent, is all a foundation I built in Goju Ryu which crossed right over to sub grappling, and gave me a huge advantage over other begginners when I first started.
Traditional Goju Ryu has a great deal of "in close" fighting, "Kakie" training (a kind of pushing hands employing aikido type submissions and judo type throws). When I first learned the arm drag in shooto I felt like I'd been doing it for years. Plus the body conditioning knoxpx mentioned, and, with the right teacher, there should be heavy sparring.
Now I'm back in the states and training BJJ, which I'm addicted to, but I wouldn't trade my foundation in Goju Ryu for anything.
