Borrowed this quote from Cliff
Also, a head that seem to be relatively undiscovered, despite being what lot's of people have asked for - Evans G Plus. It is a 12 mil (vs.10 mil) single ply with no edge damping, but the thicker mylar translates into better durability and slightly slower resonance (deeper tone).
I have used both, and for certain things, they work great.

First let me say, I'm a Rock Drummer, I've used 2ply Tom batters all my life, Until Now..........
Put these heads on a friends SonicPlus Birch kit the other day, prompted me to try them on the SClassix.
. Kinda fattened up the attack, and the drums are still very full and resonant, just a slightly softer/warmer decay, SClassix are quite bright.So I put them on the Phonic, I thought they might 'Tame' the kit, and Phonics DON'T need that
, but they didn't... Quite the opposite actually 
. Toms are huge, very full, massive in fact, and still typically Phonic, from the drivers seat .I was suspecting these heads might have a typical sound character, that, perhaps influenced a specific sound regardless of which kit they are on, but
, that's exactly what each individual model of head does , some are just considered industry standard So, I don't think these heads made my Phonic sound like my SClassix, or vice versa, but, I like 'em, just like some people like Ambassadors, others like Pinstripes, I'll report back for those interested
. Cheers
Haven't played either kit with the band, but from what I can tell thus far, if you're into 2ply Tom heads, you need to check these out
Cheers
