You guys are all so technical, I don't understand half of what you are saying! I've been using the 801 since I started vaping in March and the only thing I have done is change to a straw mod with a .5" x .5" blue foam plug which has resolved an initial flooding/ leaking issue. I get good TH & vapor, I guess I've just been lucky! Also, I go on the principle of if it ain't broke, don't fix it, so I don't blow it out, soak it or anything else untill it seems have a decrease in performance. Then I just soak in 151 grain alcohol for about a half hour, rinse in hot water, then dry for 24 hours. I'm still using the same 2 atomizers since I started! I think the Vapor Fairy has blessed me. May you always have great vapor !
