D'Addario Chromes on a P-bass had way too much of an unpleasant mid-range sound to me. They work great on a J where that mid-range compensates for the scooped sound with both pickups on full.
D'Addario Tapewounds on a J-bass just did not do anything for me. Put them back on the P where they sound fantastic.
Did not like the feel of D'Addario Half Rounds at all. Mistakenly thought they'd be like GHS Pressurewounds.
Any stainless steel round wound string I've tried in the past couple of years lasted only minutes. My jazz fusion experience ended years ago.

Prefer the warmer sound of nickel plated rounds.
Did not like Roto medium gauge flats at all at first. Gave them a second try, and now they're my go-to flat for the P. Can simply tweak the EQ to go between old school thump and a brighter, more modern sound. Love the thump of LaBella 760FL's, but need the greater versatility of the Rotos for the music I'm playing.
