Hmmm you give pretty short shrift to all the VVs that aren't variable wattage and there are some good ones that aren't Provaris despite what the Provari fanboys say.
One question though I've seen an EVO and a 3VO and I'll be darned if I can tell the difference. Can you?
Kyi just to explain. The EVO and 3VOs are VV
mods but, not your usual ones. You can choose between 4 fixed voltage settings. They aren't infinitely adjustable between the upper and lower end like most VVs.
Right now, I'm tempted to say hold off a bit before spending the money on a high end VV. There seem to be a lot of new things in that realm. The new 4 amp lavatubes look pretty promising. There's also a Provari knock off called the Vmax that appears to be a real power house. I'm a little concerned that that one will damage
batteries cranked up but, it looks interesting. I'd wait for the V2 on that one though. It has some really weird drawbacks right now.
