I did see someone from Ovale or another supplier mention that if you're getting leaking, flooding, etc. that the ego-c works best (with less issues) if you take long, slow draws on it. I'm adjusting to this myself as it is so different from the Kr808s I started on. Cooler vape, less flavor on inhale, more on exhale. It's weird because I was immediately disappointed with the muted flavor on inhale, and noticed I have to swirl the vapor around in my mouth more like a cigar to get any decent flavor. I ordered some LR attys and am hoping for the best.
Oh, and you can block the air inlets at the bottom of the atty base to limit the amount of air in your vape. (I used to do this on occasion with the 808) However, I'm unsure how that will effect things in the long run.
