The Evans ECS2 are 2ply heads with an internal dampening ring which gives a controlled focused attack, but still allowing the fundamental tone to shine with just enough sustain without too many of the unwanted overtones. These heads are roughly the equivalent of the Remo Pinstripes, however, I've found the Pinstripes to be too dull and dead sounding. I like to tune my drums towards the lower end but to still have resonance and sustain and not sound too thuddy. These ECS2's offer a wider tuning range than the pinstripes and are my favorite heads I've played with to date. On top of that all, they're also easy to tune!
