Excellent! So glad to hear your building is going so well. Most of my buying decisions the last 6 to 8 months have been to stock up on things that worked well for me, and are rebuildable. I only do flea power MTL. I don't chase the latest and greatest, although that sounds like fun..lol. The Naut Mini was my first tank, after my initial Ego Twist / CE4 stage, when I started vaping. I still think the Naut Mini is a great tasting set up. I just hate the thought of having to rely on buying coils. That doesn't fit my stock up plan, so I took a gamble on the little VVTF decks. It paid off. I won't have to shelf the Mini, if the deeming stuff makes life tough.
My other MTL stuff is the Tron & Ego One Megas, with the CLR coils. I've been using the same Tron tank, and rebuilding the same CLR coil for 10 months..lol. I rebuild that coil every 3 days or so. That's about 100 rebuilds on the same coil. I stocked up on 9 packs of CLRs. I had no idea they would last so long! I have a dozen of the Tron / Ego One Mega tanks.
Another MTL tank that I love is the Ehpro Kayfun Lite+V2 clone. Once I found out how well that worked for my low power MTL style, I snagged 8 of them.
The last of the deeming fleet is the Subtank Mini. It can be a little temperamental until you get the RBA wicking right, but it's a workhorse that will last a while. I soured on the STM for a while, when I was having some leaking issues, but I kept messing with it and found that with the right wicking, cutting the air to a minimum, and switching to a smaller diameter drip tip, it actually does a respectable job as a MTL tank.
I stocked up on spare parts for the KFL & STM (Fasttech), so I can keep my old tech fleet going until doomsday. My old tech junk will outlast me, I'm sure. I don't mind the bottom fill stuff. I like stick shifts and manual crank down windows too..lol. Low tech = long lasting & fixable in my book.
It feels good, knowing I can outlast the FDA if I need to. I bet you're felling good too, knowing you have the building skills to keep stuff going, if you need to. Coil getting yucky? No prob. A few inches of wire, and some cotton or rayon, and it's vape on!
