I'm ordering some new SM6 wedges and having troubles deciding what shaft to put in them. I had SM5s with KBS C Tapers in them and really loved the flight but didn't spin as much as I would've liked. I'm wondering if I would get the same feel and flight but more spin with the new KBS 610 wedge shaft? Also if I order C Tapers does Titleist put in a 8-9 iron shaft in the wedges to help with the spin or is it something I have to ask for when ordering? Thanks for your help! Wes
