These strings have the same price, but different specs. The USRSA has stats available (for non-members) for both of them, which I will cite here. Since I could not find a more recent rating than 2000, when Pacific Classic won by overall score, and no playtest/rating of the Klip, it is time for a scientific survey of our learned community. Please rate each string, on a scale of 10, in the following categories: 1) Playability, 2) Durability, and 3) Comfort. It is not necessary you have played with both. Please add comments to your ratings. The stats on each is as follows: Pacific Classic 17 Klip Legend 17 Gauge: 1.28 1.27 Stiffness: 92 113 (lbs/in) Tension loss (lbs): 6.39 9.31 By the way, if you are a USRSA member and have access to information other than what is here, please share it. Pacific is apparently coated with a durability enhancing glaze, while the Klip is not. This may lead you to conclude that the Pacific has less feel; however, it is less stiff. So the success of this post really depends on your ratings.
