If I can only have 2 (or possibly 3, max)....

Keep the Fender 51, 72 Tele and Cabronita. The others are cheaply replaced if you find the need.

The better 51 P, and Cabronita probably. Or probably sell all, and get a nice bass or two. Maybe some custom options from Warmoth.

The more I think about this , it really seems like you have a clear preference for Precision style basses.

I’m suggesting keep the Fender 72 Tele Bass, The Fender Japan 51 P, The Fender Cabronita . If you can add a 4th bass make it the Squier 51 P( if you need one with flats and one with rounds) or the Squier CV Jazz if you need that sound.

Pick one bass per string type you like. Like: the best one with flats, the best one with nickel rounds, the best one with steel rounds, etc.

Spend a month with each. Stow away all the other basses and select one for that month. Go about your playing business as usual and see if that month's instrument can do everything you want it to. If it doesn't, sell. Repeat with a different bass the next month.

I'd keep the tbird and one of fsos, probably the MIJ one.

 

[funkinbottom]

Given that all of those basses are of modest cost I'd sell them all and buy one (maybe, two) upscale basses with the proceeds.

Agree.
