I have an 95 Am Standard too, with not only the graphite stiffeners but also a thick slab ebony fretboard i put on it, and I still have trouble leeping the relief manageable. I’m going to try once more.
But if the neck of whatever bass you play can handle those, the action can be set very low, and they’re not difficult to play. I assume that if Fender built that signature bass with those strings in mind, they built it with an extra sturdy neck.
The sound of a broken in set of those on a p bass is like no other, in my opinion. The 45-105 set gets close after break- in, but not quite.
