Agreed. Fantastic, Bill... (To me, pick/flatwounds/P Bass is like the angels singing. I play with a pick only 10-15 percent of the time, but it's the right 10-15 percent, ha.)
Thanks for chiming in on this, soxhats. I'm glad to hear you agree, especially given that the LaBellas were your suggestion!
I think what I'll do is put the flats back on my crappy MIM P, and use that for practicing pickstyle. Those strings are too dark sounding on that bass played fingerstyle, but they might be fine for picking. I'll try the TIs on the new bass and see if I can get the growl back, and go from there. My favorite bass tone these days is Julie Slick's, via her Lakland Bob Glaub. I don't have her other secret weapon -- a Keeley compressor -- but my VT Bass might get me close....
