In my newbie MTL ignorance, my first RTA was a Bellus which I eventually managed to get to MTL acceptably at 15W (details if you’re interested). Flavor was awesome but the draw was still too loose and I couldn’t make it taste nice with a tight draw regardless of Watts/ID/spaced/contact/plain/twisted/Clapton/different gauge/metals coils/loose/medium/tight/Scottish/pancake/short/long/cotton/silica wicking.
I’ve since bought an Ubertoot UTA2, and a Digiflavor Siren 22 which I’ve tried in every combination mentioned above, as well as a Kabuki, so far with only 1.8 Ohm coils which apparently taste slightly better but gunk quicker. I’m now DIY mixing pretty well (badly at first) so I reckon I finally have a bit of an idea of what ‘tastes good’ for me in chocolates, cakes, fruits, menthols, tobaccos, and cigars, in mono’s (boring…yes I’m also a foodie/piss-head err epicurean) and blends.
So seeing as I now have some good MTL tanks and repeatable setups at 8-12W, and some nice replicable juices, I thought I’d set up my predominantly DL Bellus tank with a DL setup – dual Claptons 26/32G Kanthal (which incidentally took me three goes to get into the Bellus’s small chamber without shorting, details if you’re interested) and try my two current favourite juices – Pina Colada (AM vape), and Mild Sweet Cigar (PM vape) The verdict? Didn’t taste or throat hit ANY better. Sure it produced bigger clouds (subjectively twice as big?), but used 60W instead of 15W, and a directly proportional greater quantity of juice – I normally use about 1 ml/hr in my MTL tanks, this setup used 2ml in half-an-hour.
Bottom line - it appears you don’t need mega coils or Watts for good flavor or throat hit. Admittedly it’s taken MONTHS to find the right gear etc seeing as most manufacturers are aiming at the DL market (and why wouldn’t they? The money is in the consumables…), but with persistence (/ADHD/OCD) you can replace cigarettes on the cheap… Happy to share what I’ve learned so far…
edit - to be fair, and maybe it’s humans’ intimate relationship with fire, or our proclivity for getting in each others’ face, but I did rather enjoy producing obnoxiously excessive clouds… Not enough for a quarter the battery life and four times the juice consumption, but it was kinda’ fun…
