I am totally with you here. I love the rust look, but I cringe every time I clean them because it makes the towel a mess.I think you are probably right here. I went from a guy that loves rust to one that is not a fan for some reason. But yet I love the jet black look of these.
I noticed this as well with these. I don't recall doing it near as much with my SM7's. I have also noticed it much more on the dozen ProV1x that we received from Titleist. I've saved them for tournament rounds and have noticed that they seem to get 2-3 small little cuts from the grooves. Not sure if it's the covers or just the fact that for some reason I have hit a few more really crisp clean wedge shots with them. Could be just a coincidence because of that.
