What do you look for in bridges and tuners?

High mass bridges, light weight tuners?

The project I'm working on is a PJ bass:

One piece mahogony body about 5 pounds, Warmoth 2 octave
ebony board fretless neck, Duncan P and J quarter pound pickups
and Duncan Basslines 2 or 3 band active EQ.

I'm not a bass player, hence the question to you guys.
I'm not fixated on any brands, but quality is paramount.

Cheers, Will
