While the Estoc (or whatever newer tank you're using..Veco?) with the EUC ceramics does provide decent flavor, it doesn't come close to my single coil RTA or some of the RDTA's I've tried. I think something must have been off with the RDTA you tried (wicking? coil?).I`m thinking of buying a Ammit 25 RTA. I tried a RDTA out to see if the flavor was on pair with my EUC ceramic coil. I was dissapointed, much more flavor in my EUC coil. Is the rebuildable tanks a hoax?
