No I wouldn't say that. Each club or group of clubs has certain elements that should be "fit" to the golfer. Drivers should have the correct weight, length, loft, grip size, swing weight etc, and this can be done in doors for many golfers and get the results you need. Wedges need to have the correct lofts and lies but this is much harder to discern indoors. Grinds can be important depending on the golfer but really need to be addressed outdoors on grass.
Face-on driver swing from my round earlier today.
Setup: reverse K, reverse K, reverse K. No idea what I'm thinking with this forward press with the driver. From now on, I'm doing the slide the right hand down the outside of the right leg setup trick. I really really dislike when I'm making mistakes like this that aren't part of the dynamic portion of the golf swing. Feels bad man.
Hips: they desperately need to do more work. After I'm finished working on a few pieces, I'm going to this. This is such an important piece that just syncs a lot of stuff up (for any golfer). Not sure if I can point to this in some capacity to explain my slice miss, but I'd wager it is at least a small factor. I sit in front of a computer a lot so I'm going to do some work on stretching the muscles of the hip area religiously.
I'm going to start and try finishing these posts on a positive note with things I at least like. For this swing, it is my impact position as shown above. Lacking axis tilt away from the target, but that is more a product of the poor setup.
