What is YOUR favorite string???
Mine = Epic Strings
I just got it in the mail today and it is the best! I’m not sure how long they last, but they better last a long, long, long time. I can’t give them up. They make me happy. The most important thing though, is that they make me Epic. 
I’ve been using the Expert String from here. I like it better then Kitty. Smooth, easy on my fingers, doesn’t snag. I put a Kitty string on yesterday, but quickly changed it back to the Expert String.
Dragon String from Toxic Strings.
Hands down.

Crocostrings makes some really nice strings that last a really long time. Also, fat kitty has good length, thickness, soft on the fingers and just plays pretty darn good. Plus, it’s pretty inexpensive compared to most of the other brands out there.
To thin for me. I like weak response and thick, loose string. The Magic Threads by Epic Strings is da bomb!
