1st round with the TS-1's today. I can't give a full evaluation. Tee shots on the par 3's felt good and solid. I really like the feel of the KBS Tour 105 shafts. They feel a lot like the FST115's. The clubs did not always feel right in my hands. I am blaming that on the grips. Shortly after getting home I swapped them out with my preferred grips. Next round out will be a better evaluation.
