For the irons, the shafts are all the same. Even my woods have the same core size. I'm thinking a lot has to do with what tape the shop uses. Like you said, a "a couple of extra wraps" means nothing unless you know the tape used. Therefore, I will switch…

I have played 4 times in the last week.  All from the blue tees.  I am close to breaking 80 but just cant get over the hump.  The new Titleist mygame app is great for posting scores and keeping track of stats.

That particular variation of the Diamana Shaft is for LOW trajectory and low spin.
