Thanks guys!
Not having tried either, it's a hard decision. Not to look a gift horse in the mouth, I usually prefer single coils for longer battery life.
I have 2 Vivi Novas, a Mini Vivi and a recent evod (which I really like). So, the 2 iClear30's would round out my large capacity collection, enough to keep a good rotation of juices at the ready. But, owning 5 iClear16s would keep me in stealth mode for a while to come.
