Here's the deal. Two string ago I was playing with a 17g prince duraflex. Six months of hard playing later, I still hadn't broken a string and they'd stretched out so much that the tension was horrible. SO, next time I strung it with an 18g prince duraflex. This one frayed pretty substantially over the course of a month, but still felt good until I had to retire the frame :? Now I'm looking at what string to put in the new frame (same racquet) and I'm open to suggestions. I liked the playability of the 18g a lot, but durability was somewhat in question (big surprise). Clearly, I don't break strings much (once ever). I don't want to spend a ton on a string, but if there's another brand that I should check out, I'm definitely open to a change.
