I'm sure this is on here somewhere but I haven't been able to find it. I have a mini and use AW IMR 18350 and 490s, Protank 2,3, aeros, and Ibtanks. What ohm coil will give me the best performance and battery life?
What ohm coil works best with Provari?

I found the answer to my question on the Provape web sight.
The ProVari works with all types of atomizers/cartomizers and all ranges of resistance but there are some conditions that can cause issues. We suggest using atomizers with a higher resistance. The reason is when an atomizer heats up or runs dry the resistance drops very rapidly causing the ProVari to shutdown with E1/E2 alerts or to not fire the atomizer. It’s trying to protect itself and the atomizer from cooking itself. As the resistance drops its going near a short condition.
The reason low resistance atomizers were designed, was for devices that didn’t have adjustable voltage and this was a way to get more power say out of a set 3.7 volt device. By lowering the resistance it's increasing the wattage.
Since variable voltage devices hit the market and have the ability to raise the voltage, low resistance attys are no longer the best thing to use on these devices. By going with a higher resistance atty not only will you get better battery life but it will open all the voltage options that you now have access to and it gives the device some buffer room for the resistance to drop when it’s in use.
You can still get the same wattage and heat by raising the resistance and raising the voltage as you would lowering the resistance and lowering the voltage.
While you can still use low resistance atomizers or cartomizers in the 1.5-2.3 range, just note that you need to lower the voltage on the device to accommodate these types of attys.
We would recommend trying some 2.8-3.2 ohm attys and just raise up the voltage until you get the heat you want.

I still tend to like to run fairly low resistance coils. 1.2-1.5ohm. But I'm dripping rather than using rebuildable tanks most of the time and trying to mimic the performance of a mech mod @ 3.7-4.2V.. For clearomizers, it is actually getting hard to find anything over 2.1-2.5ohm these days. You wont get the full 6V on that. But you will get a pretty good vape.
You'll want to try both lower and higher resistances (with appropriate voltage settings).
Perhaps suprisingly, there IS a difference between vaping 1.7 ohms at 3.7 volts (8 watts or so) and vaping 3 ohms at 4.9 volts (also around 8 watts). The higher one might take a moment longer to heat up, the battery will likely last longer (that's a bit counter-intuitive but true), and there's a difference in the vape. Some people like lower, some like higher.
The LIMIT is the only thing to worry about if you find you like low ohms - if you go down to say 1.2 or lower, you might bump into the limits of the ProVari - that's when some people start going with mechanicals, or with 30 watt devices...
