So since this is my thread I'll just keep blithering on...
Tonight I'm foregoing the 6volt option and vaping 3.7 with my honking ikenvape standard LR 801. Man, the adjustable draw is a trip! I'll have to make a video of it. In the pictures you can see a hole in the side of the adapter. This hole leads up through the center post to the atomizer post. Air travels from the side of the adapter to the bottom of the 801 (801's air intake is through the bottom). Threaded through vertically in the adapter is a little allen head screw which, when screwed down, progressively covers the air intake hole in the side of the adapter. That's what all that business is. It works like a charm. Opened all the way up it's a super airy draw and can whistle. Cranked all the way down it's tight. Less vapor too. I haven't been able to cut it off completely though...I don't want to strip anything!
I've always liked to vape 801s though they're a finicky beast. Take a ton of juice, and you'll be vaping along super clouds and flavor and suddenly they decide they're too dry (which under other atty circumstances means flooded) and you get the most awful hit...time to put another 6 drops in and hope for the best...this is so much fun!
