Re: Fiberskyn/Skyntone on a brass snare?
I've used the Skyntone on a few of my snares, including by Ludwig 402B, and overall I like that head, but it's very open-sounding. It's about as opposite you can get if you're looking for a head that might cut overtones in a ringy brass snare.
It does sound nice, though. You just might want to have a Moongel at the ready.
If you're looking for a little more control I'd suggest a single-ply reverse dot head from whatever company you really like. I generally prefer the tone of a single ply head on metal snares but I like the little extra "meat" from a dotted head.
