The Blacktops are way nice!! That being said, maybe put away your MIA P for a bit and come back to it later... I often find myself really really liking my latest bass, nearly to the exclusion of my other axes. Typically the first to fall out of gig rotation is my '96 P... A month or so later, I'll take it out on a gig and be all "Oh yeah... THIS is what I've been missing!"... I know without a doubt which will be the last bass to leave my stable
