Brightest AND Least-Abrasive?

[takeout]

Going on my soon-come fretless Stingray. This has a thin fretboard (non-slab), which I'd like to preserve as much as possible. At the same time, I want to get the zingy Pino-ish tone out of this thing. To that end, and after much reading in this very forum, I'm thinking Slick Rounds. Sound like a winner? Fretboard saver AND ear pleaser?

Not quite the piano tone you want, but I like chromes alot. I think any strings, not matter how piano-like on a fretted bass lose some of the piano sound when there's no frets under them...fretless just kinda goes "mwop"- no matter what- ime

At the recommendation of bass strings online, I just replaced the chromes on my fretless l2k with GHS pressure wounds. I love them for just that round wound sort of punch while still smooth for my fingers and the board.
