My daughter is a +4 handicap and is going off to play D1 golf in college.  We got these last August at the Callaway headquarters in Carlsbad California for her but over the last 9 months she's picked up five to eight miles an hour of club head speed and the shafts are no longer the right flex for her newfound speed.

It was cheaper for us to actually get brand new woods with the proper shafts than it was to buy the shafts outright and replace them in the heads. The shaft in this club is an aftermarket shaft meant for better players and made with more exacting standards than the OEM stuff you would get off the rack at a retail outlet. 

The shaft is a Adila Ascent 40g R flex at 42.5in in length.  Head face shows almost no ware on it as she didn't play tournaments between November and March.

Message me if you have any other questions. There's also a five wood that I am setting up for a separate sale that is configured exactly the same as this one.
