alright. its go time. the first build leaked on me, but it did work like a dream for a full tank or so. I would assume the leak comes directly throu the other holes that the cotton is not wicked thru....but there are several factors that come into play with leaking. so I have a few minutes and instead of rebuilding my RDA coils, I want to get this damn Nautilus working properly. So I am going with your second method OP. I may wait 5 minutes or so just to see if any tips pop up before I drill this hole, because this is my last coil, the other one of course the holes are drilled lower.
