Workdays (long and busy) i just use cartos. Of late, whatever any engineer over there insists, I burn one to the first yuk, toss it, and run another. (The most recent purchases burn up faster, period, but they still usually go as long as almost a pack of cigs, so I'm good - they are nicer in some ways, too.) On weekends I get out my zillion juices, fill blanks, top cartos, make blends, whatever I feel like. Because it's fun. I tried the boiling thing, but nah. Huge hassle if you ask me. And I do the condo method when I feel like it and have time, and I fill from the top when I want a juicier carto, or am just in the mood to, and I spin most always. (And I don't care about a lot of vapor; in fact, it's a big stealth problem in movie theaters and other public places - I use the old regs I still have for that), and I hope the WOWS aren't just a VG step-up for the plume-fiends.) But I'm lighthearted about everything 'cept the possible New York ban, which isn't going to stop me, anyway.
