Nice P bass! I'm getting a P bass, too, although I feel at times that the soloed neck pickup of my Thunderbird gets close enough. Still it won't hurt to have one with flats and one with stainless rounds.

A Thunderbird tends not to be a light bass, and I feel my Epi VP is a bit heavier (and neck-heavier due to the thicker neck and larger "beak") than a 2019 Gibby. Still comfortable, though, and I especially like that the body wing joints of a Thunderbird automatically forms a big ramp or thumbrest.
