Hey all, Been playing with Confidential for about 4-5 years now. I really enjoy it, and I'm not necessarily looking to switch, but I also like to try out new strings once in a while in case something new catches my eye. I just switched to the Pure Aero so I figure it's a good time to look...

I’ve just uncovered a small stash of 4 sets of this string In 17gauge I think its been discontinued. Does anyone have any idea if its been renamed, or why it has ceased production - any comments on this string, good bad or ugly, would be appreciated.
