I'm totally convinced you can't "buy" a better game - through lessons or technology. Sure, you might hit some balls further or straighter, but you'll still screw up just as many shots if you don't improve your mental game. I've watched so many golfers takes lesson after lesson and buy driver after driver and never get better.
I'm doing my own little experiment to see if I can get down to a 2 or 3 index with most of the used clubs I started with when I took up golf 2 years ago. I have 12 year old ping zing2 irons, 7 or 8 year old Orlimar woods, and 1 old old-ball wedge. The only new clubs I bought are a driver, hybrid, and putter. I never buy balls and use what I find or get for free in tournaments. I've succeeded in reducing my index so far from 16 to 4, working entirely on attitude, visualization and concentration. No lessons, No ho-ing
If you can really play golf, you can shoot a good score with just about any clubs.
