Poor extension

[powerfader]

Did a quick search and didn't find anything quite along these lines; My problem is I've been hitting alot more draws than usual, especially off the tee and 2/3 of them are fine while the other third are horrific pull hooks. I've worked long and hard to get my club coming on an inside plane and my clubface slightly closed but I still often revert to type on impact and pull the club drastically inside. The resulting divot looks like an arrow pointing away from the ball. Anyway what I'd really like is if someone could give me a swing thought to make me extend through the ball for a few inches and not drag it inside. Any help would be greatly appreciated!

Also worth mentioning that in my whole life I have never hit a proper hook, not one, that should tell you quite a bit about my swing.

Here's two thoughts you can try to influence the clubface to be more square at impact

1) Pretend like your club will chase after the ball after you hit it: Sam Snead would use this thought to get more power out of a swing, but may help with getting the swing to track the target line better;

2) As you start the downswing, imagine your momentum will be projected in front of you, at the target. Perhaps that will influence the swing plane to orient itself more towards the target line.

Another thing you could try is weakening your grip slightly (rotating the hands counter-clockwise a little, but keep clubface square at address).
