I have seen people posting about SPPP breaking during stringing. I have a friend that uses this string and has experienced the same. I'd say he broke 2-3 half sets out of each reel he uses. Well today, he broke 3 half sets straight, in different positions of the racket so we can't blame the racquet, which is a fairly new Speedport Pro White. Then I gave him a set of 17g Pure to try. The Pure strung up fine, but when he was working on the crosses (PSGD), pop!! We both looked, shocked we saw that it was the SPPP, not even being pulled, and was already tied off. I'd like to know about others experiences. What gauges, and maybe even about other brands that have similar issues. The reel he had was the 17L, orange version.
