A lot of “how long they last” can depend on things like preference and body chemistry. That being said, I’d think you’d get at least as much life out of them as you would the D’Addario XL’s.
This is an interesting one - I have incredibly acidic hands. Even being a very clean person, I constantly have to wipe down electronics, strings, etc and really struggle with cars with leather steering wheels and shifters because of how corrosive my sweat appears to be. The SITs last longer than any other non-coated string I've tried. YMMV of course.
