Evans drum skins are top quality. The sound is perfect, they are durable and last long. I would highly recommend Evans over and above any other skin brand.
I recently switched to Hydraulic batters for all my toms; the EC2s are a classic looking and sounding clear tom batter, but the hydraulics for me are a lot rounder and fuller sounding. They decay quicker than the EC2s clears, so for my taste hydraulics are perfect. But, if you prefer longer decay and a slightly more complex set of fine overtone options in tuning, then I couldn't recommend the EC2s skins more.
Proper good old Evans.
My favourites by far :-)
