I... KNOW... EVERYTHING!! No, totally don't. Best I can tell is the mod industry's focus is controlling max wattage for vaping vegetable glycerin w additives, and flower vapes are a weird little (fucking awesome) niche. So, it's kinda like buying a stereo, where every option is 100s of watts beyond my reasonable needs. And in that context, the DNA75 (which is phasing out and transitioning to the DNA75C, w color display and different button layout) is the most supported board/chip that totally covers our needs w/o going crazy far beyond them. Interface is simple, results are reliable, on-board charging is trusted, I am satisfied. So, I've been searching for my favorite form factor - the DNA75 is in a ton of available mods, but it's too much curves and 3D-designed textures and huge logos for me, and there are small shops offering custom-CNC'd enclosures and mountings to match the board. Can you just get a $7 aluminum enclosure and attack it w a dremel? Yeah, but w my Splinter I'm down to one device, so I went a little far building the one mod for me. First, I started w the copper, because pretty, and this was the best I could find. It's heavy & beautiful, more of a party vape than an EDC. Then I went for as-much-in-as-little, and found the anodized green enclosure, which just barely fits a 26650. Finally, I found the anodized gray enclosure (link in to red in that size, think they're out of gray as they update to DNA75C patterns), designed to snugly fit an 18650. I don't think I can get any smaller or more simple, it feels great in my hand, and it's just big enough in one dimension that I can put it down on the table and the Splinter is protected from scratches. I feel done, now my only problem is I have too many mods.
