Looking to purchase some new Vokey SM4 wedges, 52. 8 and 58. 12 to go along with my j40 dual pocket cavity irons. My j40's are shafted with Project x 5.5 flighted shafts. I was looking at getting the SM4's with a custom shaft either KBS Hi-Rev or the Dynamic gold spinner shafts, I am looking to add some more spin.
