i pulled the trigger on this one, dipping my toe in the deeper waters so to speak. the stock dual coils are too airy at lower wattage to keep the flavor going. i did crank it to 70 watts, and with my 70/30 juice it roasted itself after 2 drags. i did try the nrg coils with the adapter and they were more reasonable, got fair flavor at 40-50 watts with the same juice, the stock coils barely heated at 40 watts. i have heard from some of the reviewers that you can run baby beast coils in the adapter, i have not tried that yet, but if they do drop an RTA kit for it i would probably buy it. the tank has potential, but it needs a lot tighter airflow to be a flavor chaser, it is absolutely a cloud chucker.
would not recommend running max vg on this as it had issues keeping up with 70/30 in the recommended sweet spot range, i have not tried the multi hole coil yet, waiting on some more batteries for my dual bat mods. this tank is truly thirsty in terms of juice and power.
I've been using Max VG e-juice with my Vaporesso coils w/out any issues. As far as 'roasting' the coils, they have a recommended (best) wattage range for every setting on capable devices (soft, normal & high, 'high' is also stamped on coil), these controls are on modern Vaporesso & some SMOK mods. I run the dual core on at 50W on medium w/out any issue, although haven't ordered anymore of these, got a 3 pack each of the GT6 & GT8, which are really 3 & 4 coils that'll lower the ohm level versus the 0.4 ohm GT2.
The cool thing about these coils, provided these aren't blown out or totally shot, can be used over & over again by a 12 hour soak in Everclear (
grain alcohol only) or other clear high proof liquor (it's quite normal for it to be dark afterwards.

). About halfway through the soak, use a safety pin or other thin object & gently go through each coil hole, don't force anything, just go all the way through & drop back in, helps to ensure a good cleaning. Followed by a rinse with hot water & then soak in water for another 12 hours, rinse again, blow through to dry good, and place over a heat/AC vent to dry. As an alternative to the final 12 hour water soak, it's OK place in water that's at a full boil for 2-3 minutes, turn off the heat & allow to naturally cool & then dry.
So far, haven't had to open my new coils yet, the two that came with the NRG tank & one from a SMOK BBB are on their 3rd reuse. The above method as to cleaning, I forget his name, but he's wild, crazy & reviews nearly every piece of hardware built.
He stated that the cleaning will bring these back to '90%', well mine still hits like new, can produce some massive clouds, of course, the GT2 not quite as much, yet still that $12 bottle of Everclear has paid for itself twice & haven't used one-fourths of it yet.
And as stated, have used nothing except Max VG, I don't like the PG much, makes every e-juice taste sweet, used to do 50/50 blends, couldn't tell some apart from the other ones of similar flavor.
I intend on getting that Vaporesso 200W tank, that is, unless has been superceded by a newer version. Am awaiting a Vaporesso 220W Switcher mod kit that included the same NRG tank as the Revenger X, just when I thought I had the latest, Vaporesso outdid themselves once again. Some says that although some components are interchangeable, that Vaporesso is of higher quality than SMOK, one thing for sure, pricing tends to be higher, although not as much selection.
Good Luck & hang in there, before you know it, will want to try the GT6 & 8 coils, while some may think because of their wattage, will floor one taking a vape, really both are very smooth in the 55-75W range. Before I got the Revenger X kit (won in ECF supplier contest), never went above 32.5W, Vaporesso made high wattage vaping easy for the masses.
