Interchangeable Shafts: A Rules Nightmare

Has the USGA created a monster?
frank thomas, the former technical director at the USGA has a very reasoned take on the latest trend in equipment: interchangeable shafts.
Interchangeable shafts were the talk of last week's PGA Merchandise Show in Orlando, Florida.
I wrote recently that not too many golfers understand shaft technology and that, in fact, many believe the shaft is the most important part of the club.
I then quoted the guru of club design and fitment, Tom Wishon, who shot that theory down.
Now Frank Thomas tells us why the USGA is going down a very dark alley with a nasty surprise lurking ahead.
