It that case, you'll probably like the Speed Revolution rda, single coil, 1 mm air hole, no other options. Not sure if it comes with both bf and non-bf pins, it has the bf pin installed.
I just took a look at my Origen Little rda, I am using a single hole even though the coil is set like the pictures I posted earlier.
Got it...


Definitely better than the "side saddle" 2.5mm ID coil I had in there... 12W-12.5W and it's working a lot better.
