MGS - Swinging vs. Hitting

My high [H/cap] history of SA golf is that of a Hitter (with active action of the Rt.Hand/Arm in the F/swg). I'm now working hard to convert to MGS golf. Ive trouble resolving MGS as either a Swingers action or that of a Hitters. If that of a swinger, in the F/swg, one would be pulling the clubshaft down towards the ball using the left arm/hand [rather than merely allowing the clubshaft to fall back down]. Since were supposively not doing that, does the Rt.Hand/Arm have any active input? If not, where does any power or clubhead speed come from? My ball contact is good, but I've lost 10-15 yds. per club.

Any hints from our gurus [Kevin, rofox, Satthms, etc.] to help convert me into properly implementing MGS and make it work? So far, it looks very promising - just some annoying Pulls.
