So you are saying we should hit down on it then? I think if you need a few yards play it up, if you need to hit the fairway put some spin on it. The draw back here I think is that the sole of modern drivers encourages more of a sweeping action. Agree?
I think you should go with whatever you can get the best results with consistently. The average PGA Tour golfer hits -1* down with the driver. I think the Long Driver competition is around +4* up.
The wind is what would concern me about hitting up quite a bit with a driver. Tough to gauge just how much the ball will bend even if you strike a ball flush and the wind takes over.
