I am using the resurrectors S.S. 1.7ohm on a E-power 14650. If I put 2 holes in it from the saddle valve it starts flooding after awhile and I blow it out and works good for a while and then starts the flooding again. With ONE hole it does not flood at all. I turn the SV all the way until it stops, when punching the hole. I am a very heavy vaporer, and the one I have now The Resurrectors is now 11 days in the tank and have ran about 50ml thru it so far, I can't believe it myself because, I usually burn one up in 2 days or so. These tanks are great. I think any carto will do well in the tank, but I do think if a hole/slot, is to big, or to many holes will cause flooding. Try and put one hole in the carto and see how it acts, then put 2 holes and see how that works this is the way to learn what works for you. HAPPY vaping to all.
