I also have a couple of sets (and a reel) of string that I am trying to get rid of.
They are all goldenset brand, the strings can be found on goldensettennis.com
They are good, quality strings that last a while. I bought a lot a while back and I am looking to use other string.
I currently have three types:
HexPoly 17 (reel)
(I recommend looking at the string and reviews before you decide, although based on personal experience they are worth it)
I'm selling them for $1 for 2 of any string. (Shipping is paid by buyer, so I thought it would be fair to sell them in packs so no one would feel like they were paying extra for the shipping).
