I feel your pain. I recently purchased three things that in a short and I mean short amount of time have markedly improved my playing. Let me start first by saying that my critical deficiency is impact. I am or was (you have no idea how happy I am to say was) a club flipper. I hated myself for being a club flipper. I would have put cigarettes out on my forehead to correct this problem if I thought it would have worked. Well, I got my three things and between them all I am cured. Yes, I hit one fat like everyone else once in a while but in two weeks I made dramatic improvement and I mean dramatic. The three items were.
1. Sybervision Impact Zone with Bobby Clampett. I respect the impact zone philosophy that Bobby teaches and I agree that dynamics are what counts and not style. I know it's pricey and seems kinda hokey but there is something about it that in my humble opinion really works. Plus you can return it within thirty days if you don't like it. If you use it everyday that is plenty of time. I will do a complete review of this product in a few weeks but I will say that for me it was a worthwhile purchase.
2. Gary Wiren Impact bag. Great cause I can use it in the living room. I practice with it 15 minutes a day usually (3), 5 minute sessions.
3. Tour striker 56-degree wedge. It really does give you the feel of what a club can do for you if you let it.
The total on all this is around $400.00 which I agree is pricey but to hit a pall consistently pure and straight is so worth it. I spent $2000.00 on lessons at Golf Tec and in a year they could not do what this combination has done in 2 weeks. I hope this helps. Greg
