I have tried numerous setups in the past 4 years. I will get excited about something new thats suppose to be the next best thing. But,,,,,never fails I always end up going back to a provari topped with a 2ohm dualcoil in a tank. I am still looking for a better tank though. But, yep a provari set at 5.2v with a 2ohm dualcoil in a tank does the trick for me.
