I’m sure you were hoping for more response, but I can give you our experience, as the designers. The TS-2 has been a best seller ever since it came out. Tremendous feel and playability, and long. The technology in the face and he stronger lofts make it a great club for those needing to get back some of the distance they have lost, or just want to keep up with some of the stronger lofted options in the market. The feel is what makes it stand out, in my opinion. The STi2 is equally as good, but does have a little different profile. The lofts are not quite as strong as the TS-2’s, so depending on your clubhead speed, you might hit them slightly higher and very slightly shorter, but they are by no means short. Still strong lofts compared to traditional lofts. We have had nothing but great feedback on the STi2. It is an extremely playable and stable (forgiving) design with solid feel. A great value, I might add, at the price as well.
