There is no "right" resistance that you have to use with the variable voltage battery. The reason that 3.0 ohms is recommended is simply that you have more play at the upper end of the voltage setting, but I use the Triton vv with the stock 2.2 - 2.4 Triton tanks just fine.
As far as the 2.6 - 2.8 ohm coils, they may actually be preferred by some with the standard Triton batts, some will prefer a hotter-hitting coil...it is all a matter of taste.
Thank you. Finally! Respectfully, I see a lot of noobs obsessing over this issue when in fact, in many cases, its a waste of time and money for them. IMHO here is the litmus test for noobs:
Fully charge a non regulated bat like the 650. Load your juice and Triton tank (with the standard/default heads-2.2 to 2.4) and Vape and consume juice: a significant portion of the juice and depleate the bats charge until it refuses to fire the tank. Perform this test with a couple of your juices over a period of days.
Then answer this question:
Did the juice/vape taste about the same during your vaping session with the conditions above? If your answer is yes then any discussion or obsessing or purchases or experimentation with other heads is a waste of your time, money, and energy and will only frustrate you. Your taste buds have not yet recovered from smoking. Your buds are nuked. That's fine and to be expected and part of the vaping journey that we all went through.
On the other side of the coin, ask others or me whose buds have recovered to a point where they CAN TELL the difference across multiple juices in the vape taste from a freshly charged non regulated bat to it's depleated state with the conditions I posted above. Often refered to as the "sweet spot" when using a non regulated bat.
