i am going to be ordering some Devine Tribes donuts and cups soon. my goal is to see if i notice any difference in flavor between these and my Ti coils. i personally do not believe that i am getting any metal taste from my Ti coils because of the TC. i just dont believe the Ti is getting hot enough to put off a metal flavor. so i want to try the ceramic donut route. problem with the ceramic donuts is they they dont wick oil. it will splatter or just run off the donut when heated. i know that is why the cup is there, but i gotta find out for myself. when i get everything ill do side by side comparisons and will share what i find with pics. oh and here are better pics of my coils. still searching for a good name for them. as you can see from the pics the oil hides in the nooks and crannies of this coil. the side shot shows you the reservoir the two coils created when put together. also note that the clapton coil is wrapped "loosely" to provide space for the inner coils leads to wrap onto.
