I dont know if I'm the only one but whenever I pop strings it's all three of them on the same day. I mean after 2 weeks I popped a Poly/SynGut hybrid, a full synthetic, and then a full poly. The weird thing was that I have only been using Poly/Synthetic hybrid more out of all of them yet after playing a couple sets the sythetic gut and poly pop like as if they were being worn out for a while. I'm going to go broke if I do this. I am going to try a 18 g kevlar/17g Synthetic hybrid to see how that goes.
