So I've been experimenting a lot lately with a ton of strings, none of them had been as good as PSGD until I tried Head RIP Control. At the beginning it was just as good if not better than PSGD but as a multifilament it's not that durable. I also like Prince Lightning XX but I just strung it and not sure of it's durability. PSGD is a monofilament syn gut with out wraps giving it durability, spin, control, and a decent amount of power but not too overwhelming. I have strung all these strings at 61 lbs, so my question is, is there a string out there that can rival PSGD? It is the number one selling string.
