Wore out my 655TM's so I purchased all 3 of these heads and paired them with Rifle spinner shafts. By simply changing hand position on my swing, I find that I can drop & stop each wedge, or fly the pin and spin it back, both with great ease. The heads are softer and more responsive than the 655's and fit my 675C iron set nicely. The Spinner shafts in combination with these heads gives me an excellent feel for full and less than full shots. Distance control is very good. Overall, I'd rate these wedges as the best I've hit yet.
