You could always buy yourself a cheap lava tube if you wanted VV vaping.
Had all the mods you speak of but only kept the provari to test my atomisers (yes I know it's an expensive multimeter) but what I find is I use my GG line and the lava tube more than anything.
Lava tubes are great for what they are, cheap and cheerfull.
I never got on to good with AVS or the UFS but loved my iattys before I sold them on to buy 4 odyseuss, oddy is a must buy but don't be taken in by somebody selling it for double it's price as you will find one or two real vapers out their who aren't here to just make a fast buck
