Love the Dvarw's. One of my favorite RTA's too.
The Dvarw MTL is my preferred. I have a couple setup w/default AF and a couple setup with the 2.5mm AF. With the 2.5mm AF I get a very nice smooth RDL and also Frankenvape as our
@AngeNZ would say. I have them running w/the 3.5ml tank sections.
Wire posts, yep.

Best I've been able to manage is LV 26/36 316L clapton, with checking connections to posts every wicking. Otherwise I like LV 28/36 316L claptons in them as they hold very sound.
ETA: Yes, yes and yes ... they just work!
