Anyway, Iacas you say the only way to hit it out of my shadow is to use my wrists. Front 9 today my drives were 240 meters, 200(into the scrub!!), 260(drove to 15 meters of the front of the green) then 287 meters(wind assisted, good bounce). So my front wrist in these swings is as firm as I can make it without losing the ability to hinge at the elbow.
I think you are cocking your wrists, even if you don't think so. A video would be nice.
As to how instructors should teach and maybe use MGS for those who don't want to put in as much effort... I don't buy it. I think that the average person can learn to play decent golf with a "traditional" swing, even if they don't have tons of time.
