My two cents. Sub-ohm vaping does not equal less flavor. You need the right device. I have an Aromamizer Plus running in the 20 ml setup and it currently sits as my favourite atty. I am running the RX 300 because it has the 4 battery setup, to my knowledge, no other device other than Smok has a 4 battery device.
I am running stainless steel coils because they can run in either temp control or non temp control, depending on whether I feel like messing with TC.
I am running dual coil alien coils from advanced vape supply (they are $16 for two coils) and measure .1 ohms, clip the leads, screw into the holes, wick, wet, drop deck in, fill tank, all in less than 7 minutes. I get amazing flavour and I only vape at 60-80 watts. I should add, the airflow is almost completely closed, which gives me the ability to do direct lung hits.
I vape 60/40 PG/VG with 6 mg of nic. Plenty of throat hit (actually more than I currently want, going to make some tweaks at some point to my eliquid) and I get the nic kick I need. I cant imagine vaping 48 mg liquid, considering a standard cigarette is around 12 mg.
I am so conscious about flavour that I rewick every day. My favourite tank before the Aromamizer Plus? The hurricane...
Where I think the industry has a problem right now is battery life and juice prices. While these devices continue to use more and more juice (remember the days when 2-3 ml a day was considered normal?), juice prices have continued to sky rocket.
I have been ordering my juice from e-liq.com because they have, bar none, the best prices I have ever seen for liquid. It isnt even close. Around $20-30 for a liter (1000 millieters) (their pricing is a bit weird, flavour, nic content, and PG/VG ratio all affect the price slightly). Want a gallon (almost 4000 millileters)? Thats going to run you around $70.
Batteries are another problem. Instead of moving to 26650s or even larger capacity batteries, like a 32650 (about the size of a D battery but about 10% longer, with a capacity of around 6000 mah), we continue to just add 18650's. This creates giant mods that are much bigger than they need to be. What if we went back to tubes that used 2 stacked 32650s? About the size of an old flash light that used 2 D batteries (actually, probably shorter because the tank would be shorter than the light bulb bit was on the older flashlight), tanks could be 40 mm in diameter, which would mean that to get a 20 ml capacity for an all day vape, your tank wouldnt be nearly as tall. Yes, it would be a huge mod as far as length, but it would be much more comfortable to hold in the hand, and look less like a giant block.
Along the same lines of batteries, 2 amp charging and a C-type USB connector and a charging dock so I can just drop my mod on a dock to charge it (the USB port for those times when Im out of town and dont have the dock).
Oh, and can we get custom firmware? Open source it so people can get in there and really customize these devices. Trust me, the community has more time than these companies, and, more incentive to put as many features and functionality into a device as possible.
I want to fill my device at 7 AM with a fully charged set of batteries, go to work, go to the college campus after work, come home, do my homework and put it on the charger when I go to bed. I dont want to carry around extra juice, I dont want to carry spare batteries or USB battery packs. Blech. Give me a device that will work for 16-18 hours.
