Awesome thanks guys I'm soaked! I've got a v2, and I like the build quality as far as being ss n glass over the kayfuns, as well as the open draw I think dual coils with their positioning and the positioning of the air holes will make this thing a winner. S should have pics in a few days!
Throw some pics up if you've got any

Here's a pic from one of my first builds....and I've since learned a thing or two about it....

This build came to .96Ω It did OK, but just wasn't "foggy" enough for me. Current build reads at .47Ω using 5/64" micros with 28ga wire. (Sorry, no pics of this one) My tendency is to want to build larger coils for these things, but the limiting factor seems to be the size of the juice channels. They are not as big as the Aqua, and the cotton wick for a 5/64" coil seems to be just about right for the V4. What has worked best for me, as has been mentioned in the other thread, is to not run your cotton all the way down the juice channels. About 1/3 to 1/2 way down is working well, with no dry hits or flooding.
What I haven't seen mentioned before, and is something I've noticed, is that it's best not to overfill the thing. Wicking issues seem to develop if it's overfilled. I like to fill it (when it's upside down) to just below the rim of the base, still leaving some air space in the tank. It still holds a ton of liquid.
