They have a few decks out now. The double coil deck is crap IMO. Tiny screws for you to trap under. The Clapton deck is also dual coil, but is designed better. Still a crew trapping design, but with lips that help trap the wire better. Theres a tri coil designed deck that looks cool, but I heard building and wicking is a pain in the ass (no personal experience on that one).
My favorite (albeit, subjective) is the original single coil RBA. Im not a fan of screw trapping, but this one has a post hole design. The holes are on the small side (I want to say around 1mm), but theres enough deck room to drill it out. Ive drilled mine out to about 2.5mm. Large enough that I can fit claptons and some crazy twisted stuff in there. Still, the dome isn't huge, so going with ultra thick wires will leave you shorting out on it (been there, done that).
Best build Ive had in it was a 6 wrap 20g Kanthal with a 3mm inner diameter. Ive tried lots of builds, and that's the one I keep running back to.
