I started off with drop in coil tanks having had two come with mods I bought. One was an ELeaf iJust 2, the other a Melo 3. I then tried a Nautilus, obviously that's an MTL clearo so different style. I always found the flavour dropped down really fast after a day or two of use and never had good results trying to wash and re-use the coils. Got so bad bad for me I even dropped of vape use for ages as I got bored with the lack of flavour plus I was getting through coils at an alarming rate.
Changed over then to an RTA (Ammit 25) and an RDTA (DeJaVu) and WOW what a difference. I don't get anything even close to the flavour from the sub-ohm tanks, except maybe briefly, when I insert a new coil, even then it's muted compared to the RTA / RDTA. I still keep the tanks (for now anyway) but not sure I'll buy any more coils for them, might even end up selling them or giving them away. The Nautilus I keep for when I'm in the mood, which is rare plus I find the Nautilus has to be gently nursed with the break in of a new coil to save burning it. Now eagerly awaiting 2 new RDAs, one bottom airflow (a Wotofo Lush Plus) and a side flow (Digiflavour Drop).
Interestingly I did wonder if some of my early exploits with clearomizers may have been responsible for poor results. Recently I had some discussion on a Thai vape forum about trying to establish a rough voltage at which self built coils on an RDA / RTS would be almost likely to give a burnt coil / dry hit. For me, the 'equation' works out at around 5v, to be one the safe side. I might not always want to vape drawing so many volts, just gives a good starting point as an upper limit guide. I normally start it off at around 2.5v and slowly work up, the wattage of course will vary according to the coil resistance. The equation doesn't work well with clearo coils though where the manufacturer, in my limited experience, stamps the acceptable wattage range on the coil along with the resistance. At least with the voltage guide I can see at a glance if I'm starting the coil off too high or even way too low, zero flavour on anything for me at around 2v.
So I tried digging out the Melo 3 and stuck on a brand new 0.5ohm coil. Primed it well with several drops on the airflow holes and also onto the tray at the top of the coil. Also did quite a few draws on it with the mod switched off to draw juice into the coil (some tips I picked up when I had problems with the Nautilus burning out coils), let it sit for 10 minutes, few more unpowered draws then fired up the mod and worked slowly up from around 20w to bed the coil in. Gradually took it up to 50w (about the limit for me as the juice gets way to sweet and the vape too hot for my liking) and backed off, settling between 30-40w. Pretty damn good
Not sure how long that coil will last before the flavour drops off though, we'll see. So the Melo is back in rotation, nice and small with a Pico iStick too. I'm aware that the Melo 3, for a clearo, is considered by some to be a very good tank and can cope with the thicker juices too. So I guess a lot can be down to pilot error too.
