I came to the exact same conclusion over time.
I own 3 p basses, one with flats and a sound of the 60's, one with flat with a modern sound, one with rounds with a 70's sound.
I also own 2 jazz basses, one with flats and one with rounds.
This way, I can adapt to almost any type of music and bands.
My thinking exactly. You can definitely cover a lot of ground with that collection!
I should probably also have added soloist/virtuoso bass players to my list. Most of those players will probably want a kind of tone that a P-bass (or a Fender-style bass in general) just can't deliver. But I'm willing to bet that most of these players still own a P-bass, or at least have owned one at some point in their career.
