There is no better club on a cost basis than the STi2. When healthy I play to an honest 12 mostly because I putt like a blind man in the dark and several guys I have played with who are better than I am use those. I swing the KE4 Tour+ because it’s easier to swing weight and a bit more stable on toe shots. Their current line up is outstanding with the new KE4 Max being the newest hit. I haven’t tried it yet but it has almost universally good reviews.
