Here's a good link. I'm not saying its scientific testing but certainly accurately reflects my own experience.
I guess I have to start with the disclaimer that I'm not 'having a go' but -
1. AR never made the tour
2. even after his testing he uses 44.5"
3. his testing was soooo flawed it's irrelevant (different shafts in different heads!)
4. he states in the article "Having tested a few golfers with shorter shafts it seems to me that each golfer has a ‘threshold’ length – an ideal length that gives them the optimal combination of speed and accuracy. For some that threshold could be 46″ while for others they perform best with a 42″ driver."
Can we just agree that the average driver length on the main male tour is less than the shaft length on most retail drivers today, as a 'fact'
If you find 43" the right length for your driver, then great, if you follow the really great club fitters (like Tom Wishon) you will no doubt be using a loft of 12 or 13 degree to go with it......but that's another discussion.
