The Score LT weights 117 grams at 41" raw length and is designed for a high ball flight. The KBS Tour 90 is 101 & 102 grams at 41.25" raw length and designed for a mid/high ball flight. I have hit them both an personally like the feel from the Score LT a little better then the KBS Tour 90. The difference in ball flight was not a big difference.
