I liked the looks of the heads right away, so I ordered the pitching wedge, 9 & 8 iron heads, ones that I happen to use most frequently as well as KBS Tour 105 regular shafts. The shafts were tipped as per the chart and butt trimmed to the standard playing length. I dry fitted them together and taped on a Golf Pride Tour Velvet midsize grip and put them on the swing weight machine. I was surprised at the outcome. The 8 iron came out as a C6, the 9 iron a C8 and the PW a D0. A pretty large discrepancy in my view for a purportedly top quality iron head. I play D2 irons, so the 8 iron requires 12 grams of weight which I think is a lot. The other 2 not so much but certainly more than I would have anticipated. Has anyone else experienced this with the new TS-1 heads? Your thoughts and comments would be appreciated.
