The end of the world is near..............................surprised they haven't spontaneously combusted yet!
EC is actually a lable used for a grade/type of DUPONT MYLAR, tho maybe used coincidentally as such in the call out by EVANS.
If it sounds good, lasts to your expectations and If you like it, it is good no matter what "prevailing" wisdom is offered on the internet.
Im good, all my resos are GENERA G1's
I use both with great results. But there's one thing I have to mention about Aquarian. I don't know what kind of coating they use but it's amazing. I just put fresh heads on my kit and did a gig. G2 coated on my toms and an Aquarian coated on my snare. After playing 2 sets you can see stick marks on the toms. Pretty normal stuff. But on the snare which is hit at least 10 (?) times more than the toms, not a mark. Looks brand new. Don't understand.
