WTT my strings for 1 new pair of 5 string rounds

[nboyer941]

I have two sets of flats that have only been used a handful of times (not sure on brand). I have 3 sets of well used round wound strings (I think slinkys). These are all four string sets.

I'd like to work out a trade for a new pair of strings for my ibanez btb1305. I'm open to brands, I just don't wanna spend $. I'd like to try rotosound swing bass strings.

Thx

Describe your flat wounds. What color silks? Have they been cut? How long have they been in use?
