I've been recently fitted for new shafts. The technician, at the end of the session performed a static measure from my hand down to the floor and claimed I needed 1/2" longer shafts. I replied that I've been playing standard lengths for 30 years. He replied:
"So what?" 
He said: "It's easier to reduce the length than to add length to the shaft."
I re-visit him Thursday to test and set the lie angles. I'll see.
