Need your opinion on this....

I got some d'darddio pro steels being specially ordered for me down at the local music shop, the question is I dont know whether to put them on my MIM P-bass with Quarter Pounders and a badass bridge or my new Squire fretless Jazz bass. I use them both the same amount right now. I'm learning some reggae on the p-bass and trying to get sort of a John Kahn sort of bass sound, kind of an RNB sound but something that I can also rock out to.
I'm just trying to learn the fretless right now and still searching for the right type of string for it, I guess I'm shooting for a Fernando Saunders/David J. tone.
What bass would you advise the pro steels for?

Roundwounds (especially stainless steel) and fretless don't always play nice together. Put them on your P.

[Coward Of Reali]

Yeah but the fretboard has ebanol on it and I can also get that mwah sound I cant get with my current nickels. What a dilemma

[Ampeg SVT]

P-bass+Prosteels=zingy rock

[Coward Of Reali]

Well than I think I'll try them on the fretless and get some flatwounds for the p-bass.
