TGM Shortcomings in Driving??

[jamnet]

My first post and just wondering, does anyone else have issues when it comes to driving the ball? Does TGM work really well for Iron play, but not so good for Drivers?
Before I got into TGM, about a year ago, I was a 10 handicap struggling with golf my 7 iron went about 150 yards, now I’m a 6 handicap payer with a 7 iron flying 165 to 170, and it’s all to do with compression and lag and a flat left wrist, so I agree 100% that using TGM for iron play (and actually putting) woks really well.
However, I cannot keep my driver on the golf course, it sprays all over the place, my really low scores come only when I employ “course management” which is another phrase for being too scared to hit a driver of the tee I use a 3 wood or hybrid or iron, which is no fun at all. Is there anyone else having Driver issues, can anyone point us in the right direction?
Thanks
