If you’re going to do a partial refret with SS, be certain you spec SS and not Evo wire as that’s harder than nickel but softer than SS, had a gold hue to it, so will look different from your existing frets; it’s what the Taylor factory uses.
FWIW, I’d just get the frets leveled and crowned, then you’re good for another long while before you go full refret. It’s a money saver and worthwhile to get more life out of the original frets.
