Hey guys. I've been playing drums for about 12 years but only have I been playing hard rock/metal for about 8 months. I can't help but play my guts out. I just went through two brand new Zildjian Z custom Medium crashes in about 4 months. I'm also having problems at the tail end of shows at keeping my intensity up. I know I'm a little out of shape but are there any tips you might have on how I can still hit hard and get into the music the way I want to and not wear out before the end of a show?
