I bought a Microgel Prestige Pro last weekend and had the local shop string up with NXT at 58. Brought it out for beer league doubles last night and popped a string at the top of the bed a little over an hour into play. The break didn't happen at the knot, so it I don't think it was stringer error. I took it back to my local shop today, ready to lobby for a credit. The head stringer shook his head, said they had a "bad batch," three or four other people had similar problems, and the stringer had even broken the string twice recently during stringing. I just wanted to see if this is a local deal or a common problem. NXT had never caused me problems the first few times I used it and I was happy I had found a multi I like.
