Hey Roger, I have heard nothing but good things about the Super Speed, are you seeing a increased Club Head speed?
If you are confident in your mechanics and your body is prepared for the added stress of swinging really fast I can't recommend it higher. I did it last year for about 12-14 weeks and was hitting the ball much farther. A couple minor injuries (don't believe related to the training) and laziness and lapses in technique and I am back about where I started.
