I personally believe fitting is overrated. Especially for the high handicap golfer.
First of all, why would a high handicapper want a clubs that fits his swing when he probably has serious issues with his swing?
Second, how much difference can 1* degree of lie angle really make when you are on the course, especially if you don't have a dialed in swing? I mean really it's 1*! That 1* can be added and subtracted based on a million different variables on the course such as, what shoes you are wearing, hard ground or soft ground, ball above/below your feet, the angle of your posture has changed by 1*, or you are gripping the club with 1/2" of variation between shots, some little change in your swing path, etc.
Third, isn't golf a sport? Which would mean you would have to adapt to various situations. How many times on the golf course do you actually want to hit a club with the exact same swing you put on it when getting fit in the store? Aren't you usually trying to push a club a little farther, ease a little shorter, nock it down below the wind, launch high to help it stop, etc? So who cares which club gives you an extra couple degrees of launch angle or 5 yards of distance.
Lastly, are those spin revs or extra 5 yards with your irons the reason your score is so high? I doubt it. Most of us have a club to hit the ball whatever distance we want, unfortunately we don't always hit it as good as we want. And our error is what causes the shot to be off.
So that is my rant. I think it is important to have consistency within your set and have clubs that are close to your static fit and at a length you can control the head, but other than that most of the other stuff should be a concern of only the best golfers.
Most of this is concerned with iron fittings btw.
