To start learning the 10th Planet System!! I ordered Eddie's DVD set "Mastering the Rubber Guard" while deployed overseas last year because I didn't have a very dangerous game from my back. Now I continue to learn the system and am very confident/dangerous on my back. Still have a long way to go in "mastering" the system, obviously, however, I'm doing well in tourneys and have my first MMA fight in two weeks at the young age of 43. Gotta love 10th Planet!! In addition to 10th Planet, drill repetition, drill repitition, drill repition. The technique needs to become muscle memory so you instictively execute without having to think.
