haha, this thread....i almost wish I'd seen it before I went crazy and spent tons of money on various enail setups....started with a dnail controller, ended up building my own controllers which I'm hoping to start selling.
i've gone through so many of these "next gen" solutions myself though, it's been crazy.
sapphire disks, quartz banger enailz, ceramic enails, quartz castle style, the standard quartz hole-in-center style, and the genesis nail from happy daddy....not to mention a bunch of quartz carb caps, titanium carb caps, and the whole bit.....
i've also got a 20mm and flat coil right now, but I've got a bunch more coils on the way, well, partly cause I'm selling some, but also cause I still secretly want a 16 so I have a set of each size for myself, haha...I've tried so many different enails now it's not funny...
i started with quartz hole-in-the center, you know, the standard quartz nail, pukinbeagle makes em, china clones em, they're a dime a dozen. Not a fan of this style nail in quartz or ti honestly. I like dunking and I always end up dropping it down the hole and wasting it, haha. they're tolerable I guess, but then I see companies selling "deep dish" versions of things like this and i'm like why? this is not what I want...I want wide-open, not narrow and deep....
I moved onto the quartz bangers from there, and these are really one my favorite enail designs. The heat waste is minimal, since the airflow isn't really going around the coil, and the coil is usually directly around the bowl, plus with a huge dabbing area, it's hard to miss if you're just dropping in dunks. i think overall this is as good as it gets for a quartz nail, there's some room for improvement in terms of claim catching and I've got a friend looking into it for me, we'll see if I ever get my claim catching quartz banger made...
I tried ceramic, the taste was great, but it seemed to leave the most resin stuck on my glass out of any of my nails. I don't know why that is, maybe temperature too low, too high, something, but I just found myself cleaning my rig constantly with ceramic nails. I also found cleaning the nail itself to be slightly more annoying than the other options. Overall, I think I'm over ceramic...I still want to try a flat-coil style ceramic though. I have a 20mm hive....
the quartz castles are just flawed. the bowl/dab area is isolated from the coil like a thermos or something. I mean, I know that's just sort of how you have to make it, but, when you dab off these, the temperature has a tendency to fluctuate, and you end up wanting to run the whole thing a lot hotter to compensate. I did manage to find a quartz pukinbeagle carb cap that fit onto mine just perfectly, and that really did improve the experience, but overall, I'm not impressed. I was considering selling mine...
the sapphire discs are nice I guess...I mean, I don't know if they do anything special. My favorite thing to do was to load it up with a dab on it and drop it onto the nail....if all you had was a infinti then i'd probably want one of these....but i mean, if you have anything that isn't titanium it's probably pointless.
i'm pretty much a fan of the genesis now as my daily driver. I wasn't at first, I even have a friend who hates them, but after using all my various nails on my main rig, you start to see which nails are leaving the most resin on your pieces, and which ones are getting the most out of things.....needless to say, I clean my rig much less and it seems whatever 'reclaim catching' magic the design claims to have has some truth to it, the main flaw with the design is that the temperature difference between the quartz insert and the surrounding titanium is massive, i mean, it's like a burnt dab vs a perfect dab if you miss the quartz, that also means you have to turn the heat up a bit more than you'd expect for a quartz nail, meanwhile if you turn it down so the titanium is cooler, the quartz won't be hot enough anymore, so there's that. I think there's room for improvement. the carb cap also has a tendency to get your dab material stuck to it when you put it on, since it sits so close to the bowl, really, all minor flaws, and at first they drove me away a bit, but, when you use it right....it's been nice....really nice....using the flat coil with mine....never got a chance to try the 20/16mm adapters...
go snag one before they are gone!
That's why I went and got the one with the hook from CFAB. My normal banger is strictly for travel and torch use now
