Ok so I just bought a Michael Kelly dragonfly fretless acoustic-electric 5 string bass. I want strings that will not damage the frets, and still sound amazing. The thing is that fender only makes their nylon tapewounds for four sting basses, so if i end up going with fender then I would have to buys Roto's 135 gauge string for the 5th string(if that woud even work?). Or should I should just go with the full set of Roto's? At the end of the day both options are the same price. I've just heard good things about the fender strings thats why i would go though the extra hassle, but have also heard a lot of good things about the Roto's.

Please help me. Thank you!
