Cobalt Flats Question

[Monahan]

Originally asked this question over in the bass section, but this may be a more appropriate place to post:

Question for those using cobalt flats:
Anyone notice unusual fret-wear when using cobalt flats?

As I understand it, cobalt ranks higher on the hardness scale than stainless steel. According to the string packaging, cobalt is used for the outer ribbon and underwraps. So my tendency of overthinking engages; theoretically, a string constructed of material harder than that of the frets should wear the frets quicker than strings made of softer material.

Thanks all!

Anyone?

Bueller?

I've used cobalts for a few years on a couple of guitars with SS frets. I have not noticed any wear.
