I hope I didn't run you off with my brief answer.

If you're fading the ball (5 yards movement) then I would say that perhaps more heel-weighted drivers would help you straighten out. But if you're fading the ball, your sense of feel is probably better, too; and your proprioception will pickup on the weighting change and change your ball flight - I've played with players like this, who can detect the 'undetectable' changes (ie tip weights, hosel weights) and his ball flight gets more draw-influenced the more weight is heel side. Granted, he can also hit balls with his eyes closed and tell you what his ball is doing.

For the average golfer with average feel (cannot detect a weight change equivalent to taping a quarter on the head), there's not enough feel to warrant changing where the weight is.

If you're having a slice problem, you're further ahead to get a closed face driver (most are nowadays) but - and this is important - let it sit closed at address. Then take your normal grip and make your normal swing.

A new highlight: Golfing the home course on Christmas Day.

I say it too often: If it's golf club shaped, you can play with it.

For the record, I'm a club doctor, not a swing doctor.
