It's just that its a little hard to believe. If you are hitting your 4h that far, that means you have to hit it about as pure and you can, not to mention have some ungodly swing speed. With that kind of swing speed, you should be able to hit a driver farther than 150 yards, even with a wicked slice. And I'm pretty sure Tiger and Phil don't hit thier 4h that far. Now for a tip. A slice to me means one of two things. Your cutting across the ball or your club face is open at contact or a combo of both which is worse yet. When you go to the range, start with nice easy swings. You would be suprised how far the ball will go with a 50% swing as long as you are hitting it in the sweet spot. From there build up your speed as you are getting more comfortable. When I start out with my driver on the range I always try to hit it 200 yards to get a good feel and warm up. Good luck!
