I've been switching back and forth betweem a 901 Prodigy and a 510 Protege. I've been dripping, and after 2 or three good puffs, I was getting a scorched flavor out of any juice I tried, even the HV juice. On a whim, I decided to tailpipe. I think the more concentrated draw on the atty must have cleaned some gunk off of them, because now they work great. Even my homemade juice doesn't burn. Maybe it has to do with the increase in air through the atty. Yes, the attys get hot on my lips, but I just have to let off for a couple of minutes and it's fine. Come to think of it, analogs were hot on my lips, too. Anyway, hope this helps someone. Give it a shot and let me know if anyone else has a similar experience.
