I have this rda and yes! it is a pita! to build on and ive built a lot of builds on lots of dif attys
Heres a pic of a build i did-->
i think i only rebuilt that rda twice and i think the first time was 28g and that in the pic maybe 26g, i havent bothered with it for a long time, i have a couple of phenotype-L rda's which are my fav at the mo and are so easy to build on you can prob do it blind folded

But back to the fishbone! the main priority for me when i was building the it was to get the coils directly over the top of the airflow slots and to make sure after wicking it that the air could escape underneath and behind the coils also and it tasted pretty good But as said i dont think it was worth the hassle in the end
