Slicing's very destructive for the confidence, you'll end up doing it with all the clubs if you dont curb it, by all means get a draw driver or offset driver, at least your doing something positive about it and that helps with the internal mind games.
What it will probably also teach you is that your swing plane is all to cock, with too steep a swing coming into the ball as the forearms have been thrown out a bit too far from the body forcing you across the line and hitting the ball off the heel.
There are as has been mentioned here, and elsewhere, lots of symptoms regarding a slice and its level of severity, it always comes down to swing plane and a healthy backswing and tempo, lessons can help a great deal but they must be made to pay else your back where you started from five minutes down the road.
Why is it so easy to hit a slice and so hard to hit it straight? Bloody stupid game.
