The Tour SL are slightly lighter, depending on the flex you have, and lowering the overall weight of the club can help increase clubhead speed resulting in more distance. That being said, there is not enough difference in the shaft weight between these two to gain 10 to 15 yards. For reference, a 1 mph increase in clubhead speed will yield approx. 2.3 yards. It takes 30 grams of shaft weight reduction to pick up 1.5 mph in clubhead speed and 1 inch in club length to to pick up 1 mph in cluhead speed. If you did try the lighter shaft and lengthen the playing length of your clubs, you could possibly pick up a few yards, but 10 to 15 yards is a lot for a shaft change with only a few grams of weight difference.
