Yeah the Doge and the MutationX are probably right up the alley for cloud chasers. As the airflow on BOTH is absolutely insane. The Doge in my opinion is my preferred atty over the MutationX just because of the heat fins, which DO in fact work. I know a lot of RDA's lack any sufficient cooling, the Doge - opened up (dual coil mode - wide open) I believe has a 10mm+ airflow setup (which is TOO airy for most) - but she produces the clouds without burning your lips, lungs, or throat. The standard post (before swapping) is a copper post with a copper 510 pin. I have mine swapped out for the stainless post - which works fine. My only complaints about the Doge RDA are the following:
The center post has a tendency to turn easily - the fix - when tightening the post screw down - hold a flathead into the bottom pin and THEN try tightening the post screw.
Limited drip tip usage - I just press fit my Vapelyfe wide bore into it. Until I press fit it into the heat sink cap (halo cap - top cap - drip tip cap - whatever you want to call it) it would stop at the 3/4 mark and would occasionally fall out. The drip tip is now stuck permanently in the cap. Which is fine - I have a box full of wide bore drip tips from various companies. I just prefer my Vapelyfe tips over everything else. Plus brass -> stainless -> brass -> stainless -> brass looks beast IMO.
Designed here in the US - outsourced in China. This can be a problem. As I own 2 of these RDA's already - and although I love them - some of the parts are NOT compatible with each other - I have a spare stainless post that wont allow the threading of ANY screws into it - yet the one post I have works on a handful of screws here and there. They are relatively inexpensive (compared to some of the other devices and atomizers I use frequently) but this shouldn't happen - at all - regardless of where they're manufactured.
The heat sink fins are pretty sharp. It took the whole top layer of skin off my finger once while trying to prove a point that my drip tip was stuck - for life. So be careful.
What I love about the Doge:
Flavor - once you pop the heat sink cap off of it, give it a turn upside down and have a look for yourself. Its conical. Which somehow not only helps evenly distribute heat - but also plays a role in flavor production.
No heat - no matter how hard you vape this thing - I've chain pulled 20+ times to get it to get hot - nothing. The only thing that got hot was the vapor after like pull 22. The coils were burning up at that point - but i continued to stay the course and pull the hell out of it. The heat sink cap was still safe to touch and although warm - nothing like grabbing the top cap of some atty's *cough* Mephisto *cough* where it would just plain burn the .... out of you.
SPARE PARTS! Literally you could rebuild this thing from the ground up at least 5-6 times before you need spare parts. My baggy came with a micro screw driver, 8 o-rings, 3 sets of spare insulators, 3 sets of spare screws, a stainless steel center post, and my god, a spare copper 510 pin. Who throws an extra 510 pin into their case anymore? These guys did apparently.
Easy of building - it's simple. I still prefer my Mephisto when working with 18AWG and lower wire. But this atty will support dual coil 20AWG easily. The post holes are pretty clean and a pretty good size. So have no fear in building it.
Makes contact with everything I have - granted MY 510 pin is almost flush due to tightening it so much - it used to protrude out a bit, but it made solid connections all the time, every time, and still does so.
