I use these picks primarily for strumming, but they have a great grip, and work great. I doubt they'll ever wear out, and though I use .60-.80 for whatever I'm doing on my acoustics, these are among my favorite picks, and I use these the Clayton's, and a few others, but for .60 picks these are really nice, and I tend to pick them out of the box when I start to warm up with a pick.
