I finally got my Themis dual coil version in black today and it meets my expectations, flavor is really up there with the best I've had in a tank. A lot less spit back than I get in my Zeus tanks which is also a plus (actually haven't gotten any spit back - an effect I usually attribute to duals being off the center post line), although I will say this is a BIG tank, it dwarfs even my Bravo's with the bubble glass. All in all, I'd say this is the leak proof dual coil version of the Zeus that I was after. Airflow is a little loud but not ridiculous full open, it develops a whistle around 1/2 open which I knew about ahead of time from youtube reviews.
I put in small dual 3mm SS316L quad core fused claptons, 30Gx4/40G with 7 wraps each for a final .17 Ohms build. It could easily fit bigger coils, both in wire size and in diameter. 3.5mm will for sure fit, I'd say even 4mm is definitely doable. The limiting factor there is going to be with the wicking, even with 3mm coils you have a lot of wick to deal with. Of course the route you want to go is to comb it out to thin it otherwise the channels will be way too packed. Then cut the wick and place it in the channels, be sure to fluff the wick before putting it in to avoid flooding (obviously won't leak but will cause gurgling). Also make sure the wick isn't too long... you want to create a dam just a bit above the holes in the juice well. Making them too long so that its completely blocking off the holes will make it so the juicewell doesn't always have juice in it and will lead to dry hits from the reviews I watched.
It was an easy build overall, it's nice having the clamp screws facing the flat side of the coil legs so I don't have to give the legs a twist off the coil to line up like in the Zeus (not that it's hard, just an extra step). I replaced the flat head grub screws with M2.5 4mm hex screws that I also use in the Zeus, its a personal preference thing but I prefer them. I'm not a giant fan of the 2 piece deck, it makes it a bit awkward during the build process and a bit messy when priming the coil, but I can live with it and I'm sure it'll get more straightforward in time. I also am not a fan of the o-rings that go on the glass section, on the Zeus they appear to be attached to the glass, I've never had one fall off, where as these are loose, maybe after using it for a bit they'll get better joined to the mating surface but I doubt it. So far no problems with the base o-ring that seals the bottom of the build deck.
