For anyone curious about trying flat wire I experimented with my 27g flat vs round wire and found that the flat wire produced more vapor (in this build) than the round. I built the same coils the first 2 at .6 ohms and the second set at .7 ohms in the same RM2 (single coil) and it was very noticeable to everyone in the room. I'm always looking to perfect the already perfect, so newbies I am confirming the more surface area coverage theory by some, flat wire = more vapor and for me more nicotine (in theory) I hope.
More vapor/nicotine

I always preferred flat wire for making a single micro coil and you are correct, at least from what I experienced. But when I started making dual coils, it became too hard to work with and feed two coils through the same hole so I had to use a different wire. But for single coils, the flat wire rocks.
I used to build flat wire single, dual and parallel coils way back in my cloud chaser days. In the right atty's they are tropical storm creators... massive thunder clouds, torrential flavor rain and lightning bolt throat hits. Still have a few sizes of it around here but have not used it in any of my bf atty's for the Reos even though I have some that would be perfect candidates for them. Not on my bucket list though, I KISS now days.
Nice writeup, Swamper.
If you really want to rock your single coil world, try a twisted flat wire coil (provided the posts in your atty will take it).
G'head, try it. You know you wanna.

Currently, I use 28g - 6/7 wrap on 3/32 drill bit - 1.23 ohms.
I wouldn't know where to begin with using flat kanthal. Any suggestions on getting the figure above using flat? What gauge, and how many wraps?

Use the same gauge wire and your ohms will be close enough if not the same. They are both 28g, the round is flattened giving you a bit more coverage area on the wick.

I've looked here at Flat Ribbon Kanthal TemCO doesn't list flat ribbon in guauge size like they do Kanthal round wire.
This flat/round conversion chart is from Temco themselves:
edit: before I even clicked your link I found that from here: Size conversion chart for round, flat and ribbon wire: FastTech Forums - but that chart is on the page you linked to!
Sounds about right my 27g is 0.9 x 0.1 which would be a hair thicker. Never mind I see the conversion chart above.

Glad you pointed that out. I was in a hurry and overlooked it. Thanks.
