Can’t speak for the TS-1’s, but the TS-2’s are awesome. The other day I was hitting balls on my sim with the TS-2’s (my sim set), and was just hammering them. Out of curiosity, I grabbed the 8-irons from my PXG 0311XP’s, TM M5’s, and Mizuno Hot Metal 919’s to compare. The TS-2 was the longest by a fair margin, and had the best dispersion. Now mind you, all had different shafts. Nippon 1150 in the TS-2, KBS Tour in the TM, Recoil 95 in the Mizuno, and Elevate 95 in the PXG. I think I figured out my swing agrees with heavier shafts. Too bad the bounce is so low on the TS-2, they’d be back in the bag. They’re sweet on the sim tho. Look up Popeye on other forums, he seems to be the unofficial Maltby reviewer.
