I had a lot of fun playing with both the Royal1 and ProFlex1. I’m not sure if anything has changed, but they seemed so much better than many of the earlier Attack drum heads I had tried a few years ago. These heads were more versatile, open and dynamic than I expected. I can’t personally answer the question about durability but will continue to play them and see how they hold up. I should note that drummer, Rick Meadors, recently posted on drumforum.org about his experience with the Royal1 drum heads stating that, “Attack's coating is darn near indestructible in my experience… I've had that head on that snare for about 8 months now and have played it A LOT! Probably close to two dozen gigs plus a lot of playing at home during the past few months.”
