New to flats... which bass? Which Strings?

[Mike Vee]

There's no P bass so I have no idea. Maybe Optima RBs on the Ric?

OP never returned to tell us what he did. Such a tease.

I have TI's on my PJ, GHS Precision flats on my cheap Jazz and NYXL rounds on my expensive Jazz.

If I needed to buy another set of flats I'd think I'd try some heavy duty Labellas.

Skipping most of the previous comments (because I'm lazy) I use flats on all of my basses. I will be honest, I tried halfs on my Squier P-bass special (PJ) . Loved the sound, hated the feel. Put flats on and now I love the feel and hate the sound. I'll be trying labella next on that one. My SS Gretsch spunds best with rounds

Mt stepdad (gone now), moved from upright to electric, a '70s jazz. He always used flats. I have no idea what brand and it wouldn't surprise me if he never changed them.

Sound and feel. All you can to is try since it's all subjective
