My experience has always led me to single ply heads for a brighter tone. Are you sure that's a 15" snare. I ask because they are uncommon. I know Tama makes one. It's called a super piccolo I think. Anyway, I've always like Evans G1 coated on top and a Hazy 300 on the bottom for a general application musically. (AMBASSADORS top and bottom if you're going with remo). Again you may have trouble finding 15" snare side (bottom) heads. They make them, but they're hard to find.
