Oh, about the inhale. How should I hit a 510? I've heard long, slow, two step inhales is the way to go. Which wouldn't be a big switch for me because that's how I smoke analogs.
By the way, I just wanna say thank you guys a ton for all this help. You guys are awesome and I hope to stick around and become a contributing member of your wonderful community you have here
With a manual batt, I like to hit the button for a second before I start to draw, draw for two or three secs then release button and continue to draw another sec or two. If I don't do the last part I often see vapor rising from the mouthpiece and feel like I wasted perfectly good vapor hehe.
With an auto youll want to do long draws (6-8 secs ) because itll take a fraction of a second before the auto batt kicks in and starts to produce vapor.
Also, and its my opinion that this is important, I used to draw on analogs fairly hard. You don't want to do that on a manual battery. The manual is already doing all the work so all you need to do is gently draw the vapor into your mouth/lungs. For me, if I hard draw, I end up with juice in my mouth. While I need to draw harder on an auto batt, I would still end up with a juicy hit if I drew too hard.
either way you can inhale direct to lungs, but I think youll find that easier with the manual battery, though personally I think I get more flavor from my juices with a mouth to lung inhale. ( if you want to really enjoy a good juice, a slow nose exhale really seems to bring out some flavors )
hope that helps
