String noise calms down. The low mids start to poke through more as the high mids mellow. There is this "honky" mid range thing with worn rounds on a P that is a bit less pronounced with nickels than with steels (IMO). The DA's are nice because they are cheap, and the stiffness is about perfect for me.
Yes, there is a a honkiness with certain strings, perhaps it has to do with scooped mids due to the strings-Pbass combination. I've strung one of my two Pbasses with Fender 7150s pure nickel rounds to counter this honkiness. This particular Pbass (with V-Mod pickup) with these strings has a rather mids-heavy, punchy, full tone. Yet kinda modern, not old-school. Fun to play for a while.
