I don't know how to link. All I did was google Jim's swing and found 10-15 short video lessons from him. If that's to much trouble for you, then forget it. Also, you can definitely hit it fat with his swing. Out of curiosity from this thread, I found his videos, and tried it at the range. Hit it fat a few times. I think, because as a "rotational" swinger, I instinctively want to start the downswing with the "rotation" of the my body. With Jim's preload set up, by doing that my club would just dump straight to the ground. I only tried 20 or so swings. It was almost screwing up my own swing because I trying not to rotate, which is the exact opposite of every lesson I've had, my wife has had, or my (2) kids have had.
Golf is a mind game. Whatever you choose should feel good to you, make you happy, make you want to go to the range, want to play. Don't worry about finding the exact right club, worry about finding one you love, that feels good, that makes you not regret parting with the cash!
I was all Callaway, except putter, until this year. I went to the dark side. I was playing Callaway xhot2 irons, and bought a new set of Cobra SZ with recoil regular flex shafts. The jury is still out, since this isn't exactly the time for golf in Ohio. But, I've been to the simulator, and so far so good, they feel good.
I don't feel like I'm missing a lot with the XR, but the advertising for new clubs is enticing. As was suggested, I'm going to cruise the used driver market.
