I'm still getting about 21 tank fulls off of each wick job, and that's with a 3.5mm 30g twisted Kanthal coil. As long as I don't decide to change it for something different, or mess it up due to too much wick trying to be forced thru the coil, I can make my coils run for as long as 8-10 months, even with dry burns every wick change. As you all might remember, I am running in TC/TL mode with my Kanthal builds, and at 14.5 watts, so 21 tank fulls for my wicks, and about 8-10 months for my coils is not so bad, and a whole lot cheaper than buying store bought coil heads at $5 to $9 for a pack of 4 or 5 that last maybe 2 weeks before needing to be changed out for new ones. That's why I LOve re-building, well one reason anyways.
I'm doing R-DL hits off my Siren 22 (opened up to the Biggest air hole) with my Menthol/Mint DIY juice now. Great for opening up the ole sinuses. I make my own Menthol from Crystals, 66% crushed Crystals in 34% PG is pretty strong at 1.5% strength, then I add 1% INW Mint to give it a bit more flavor in my 80 PG/20 VG and 9mg/ml Nic solution with .5% Koolada added. Really helps with head colds also folks. I figure that it's better than popping a bunch of pills.
