strings for a Fender '51 Precision bass to avoid intonation problems with two-saddle bridge

[Pier_]

As a telecaster player who insist on a similar saddle,

well, for example I have a Squier CV Esquire 50's model with the 3 saddle bridge, and the Ernie Ball Regular Slinky 10-46 work perfectly and intonate on every string.
with other sets, like Elixir in the same gauge, it's not that precise, but still a good compromise, so that guitar usually gets Ernie Balls instead of my usual Elixir. is that a problem? not much, and if needed I can use the plains from Elixir (which are treated with anti rust) and the other strings from the EB set, but I'm a "clean hands" player, so my strings usually last long even if not coated.

however, I've ordered different sets to try:

Rotosound RS66LD extra long
Ernie Ball Regular slinky (50-105)
Ernie Ball Super Slinky (45-100)

I chose these three sets because the Ernie Balls usually intonate "near" on every saddle, and Rotosound because the two pairs intonate fairly near, so maybe they'll work.

I'll let you know as soon as I try them.

None. The two-saddle bridge is inferior. Flame me as you will, I stand by this, having played them. A couple of companies make bridges that fit the old '51-style plate and screw holes that accommodate this, whether by using four saddles, or two angled saddles. Back when it didn't matter, it didn't matter. But with modern digital recording that reveals every nit, flea, wart, and imperfection, to say nothing about the strings that were originally strung on these bridges no longer exist and cannot be duplicated, two-saddle bridges are obsolete.

^^THIS^^ a whole lot. I've run into the same thing, with basses that use Hofner-style bridges; Dano-style Rosewood "stick" bridges; and - to a certain extent - floating Tune-O-Matic bridges. Each individual bridge will hate some strings, and never intonate with them; or, it will 'Sorta" intonate with them; or, if GOD smiles on you, will intonate "perfectly" with them. If you find those strings? NEVER use anything else. Personally? I put up with this... nonsense... because 1) for 90% of what I play, "sorta intonated" works just fine; and 2) if I want to play those basses? I have no choice. In this case? The bridge can be replaced - and should be, if "perfect" intonation is required...
