Does NRG2 or X-One Biphase fray?

[burgerks]

Just wondering? How about movement too, do they move much?
thanks!

X-One frays big time. Movement is medium, not as bad as syn gut, more than poly.

NRG2 also frays and starts moving around a lot after a couple of hours of play. However, it's a good string if you're looking for a softer, powerful string.

In 18x20 both of them are great and dont move, but they fray, as they should because they are multies!
