Well... Out of the 27 basses I have in my "Herd", one wears Rounds (only because it pretty much has to); two wear Tapes; and all the others wear all kinds of flats. Because all flats
DO NOT sound the same. So... what kind of tone are you looking for?
- Bright? If you want flats that sound almost like rounds? Then you want - at best - EB Slinky Cobalt Flats - the lighter gauge ones. After that? D'Addario "Chromes"; although, they do darken up a lot as they age... Or, if you can find them? La Bella 760FX Flats. At 39-96 gauge, they're... Bright-ish, but there's no doubt they're still La Bella Deep Talkin' Flats... I use them on one of my long scale Dano DC59s, 'cause they're bright enough to give me the classic "Dano sound"...
- "Modern, Mid-range-y? If you don't mind the flexibility; the cost; and how long they take to break in? TI JF344 Jazz Flats are awfully hard to beat. However... if you want the same basic tone, but without the orchestral overtones that TI's are famous for - and, the cost and prolonged break-in? I recommend Fender 9050L's. I had them on my '78 P-Bass for years, and liked them. Still have them on... 3? basses... If you want to hear what P-Basses sounded like from the factory, until 1982? Try some GHS #3025 Precision Flats. That's what my P-Bass wears now - under the foam mute in the bridge cover. They are surprisingly mid-range focused flats. The heavier GHS P-Flats, however, are... less so. Pretty much any light gauge flat is in this ball park, though...
- Old School Thump? La Bella "1954 Original" DTF's (also known as "Jamerson Flats") are the King of Thump; Followed by the heavy GHS P-Flats; and, the Roto SH77LD "Steve Harris" Monel Flats. If you don't mind playing strings that are the
definition of "Bridge cable stiff" (with actual, pull-to-pitch tension to go with it)? These will make you happy. Otherwise, The "normal" Roto RS77LD Monel Flats; every other La Balla DTF (except the 760FX and FD's), and everyone else's 45-105 flats, are more than thumpy enough for most people. Some of them - especially the Gallis, Dogals and Optimas - are right on the border of "mid-range-y", but they have more low end - and noticeably less top end - than typical mid-range flats do. I use a lot of these flats...
So... which flats should you use? That, I'm afraid, is up to you...
