So I picked up a V1 in the classies a few weeks back, and it is performing flawlessly. Currently my happy vape place is running IGO-L at 1.4Ω at 3.6V, and Protank 2's at 1.8Ω at about 3.6-3.7V. This is where I have pretty much settled in with my vape routine. I have read the archived threads that I could find about upgrading to V2, and do have other ProVari V2.5's in my rotation. On quick glance around me, the room is filled with a cloud of vapor, and am satisfied with how well this unit hits, and the flavor and temperature of the vapor production. Part of me is tempted to sent it in for the upgrade, and part of me wants to keep the unit in its original "as released to the wild" state. I am more leaning towards keeping it as is, and enjoying it as is. I am kind of curious how many V1 owners are out there that are still vaping away on V1's in original "as released" condition? I don't believe that the 2.5amp to 3.5amp limit increase is going to affect me in my current setups... is there any benefit in my case to upgrade?
