Yo freddy, you should check out this site:
www.indoorstorm.com. I'm in the market for a new snare, preferrably a metal one. Noble and Cooley got some real good snares, although they're pretty pricey. I've been looking at the alloy snare in the 4.75x14 and it sounds soooooo good. The thing I like about this website is that their products have sound clips, so you can hear first hand what the product sounds like. You also can shop around their other snare selections if you don't like my suggestion. I totally feel where you're coming from about being different. My main snare is a 13" and I love it, but I don't want my next snare to be the same size in diameter or depth. I myself, have noticed that my ear prefers the sound of the warmer metal snares more than anything else. I was sleeping on brass for a very long time because I had the idea that it was waaaay brighter than steel and I hate steel snares, but after listening and comparing the different metal snares I realized that brass sounds really good. Oh, and BBD ain't lying about that aluminum, that metal sounds gooooood!
