[...] Anyone got any tips for a dripping newbie? [...]
Well, I wrote this post a while ago. It was meant for the complete noob, and it's a long way from being an exhaustive treatise on the subject. I've learned more since I wrote that, as well. I've been meaning to update that post a bit. Maybe I'll get a chance today or tomorrow.
As for how many drops, it depends on the particular juice and atty combination. I use a relatively thick juice in a 510 on a GGTS @ 6 Volts, and I "prime" a new atty with about 4 drops. When it starts to taste like it's getting dry, I put 2 more drops in 'em. If I flood it, I take the atty off and blow it out a little (no need to get it bone dry).
As for "perfection" on a 510, I don't think there is a particular number of drops that I can give you. I achieve "vaping nirvana" most often when I've got it vaping pretty well, then I set it down horizontally for a few minutes to "rest". Next time I pick it up, bam! The hard part for a chain-vaper like me, is leaving sit for a few minutes. I've been thinking of using 2 PVs in rotation, so I can get that perfect vape more often.
