Hebron's DVD is the best one I've seen , imho, for demonstrating TGM principles, although he uses very little TGM terminology. I haven't seen BD's video.
Brian's Never Hook Again video is, imho, the best instructional video ever. Doesn't teach TGM principes, but the full swing motion he teaches is by far the most effective. I've tried many of the full swing motions taught in other videos, websites, magazine, and TGC, and they are all personally too difficult to execute competently. Too many freaking moving parts and swing thoughts.
