I probably won't end up with Pros, but that "tungsten" legend is a pretty small font. I don't think I'd give it a second thought. That being said: It does strike me as kind of odd they'd make "pro" simply embossed, but they'd paint-fill "tungsten," thus making the latter somewhat more pronounced.
I assume because of the tech story. I thought I saw somewhere that it’s stamped only on the 3 - 7 irons, where they have the massive Tungsten energy core, but I could be wrong. I think it’d look sleeker without paintfill, but it doesn’t bother me at all “as is.”
