Recommend me strings based on these criteria.

[Crazy Ivan]

For a fretless Jazz.

1. Won't destroy the fingerboard faster than you can say "break out the sanding block". In other words, not RS66's.

2. As much mwah and mids as possible. I want this thing to cut right on through the mix.

3. Pronounced harmonics would be nice, as I use them a lot in solo pieces.

[GeoffByrne]

Halfwounds/groundwounds?

[Jaco who?]

You want DR Sunbeams.

[bassistgook]

Low riders nickle should do good. Tapewound also might do the trick for you if you want a little less highs.

[Versatek6]

2nd the Lo Riders.
