I've had a billy blast mesh head on my kick for 9 months, and it's holding up very well. I added two layers of patches (like for a pair of jeans), just to further reinforce the head. I did this after my billy blast snare head started to fail. If you're a heavy hitter, billy blast heads are not the way to go, unless you don't mind changing them out somewhat frequently. In contrast, there are stronger mesh products on the market, but they cost more. IMO, the ROI is better on Roland heads... that's what I've switch to (except for my kick, which is still going strong).
