I only had the VVv3 for a couple of days before my husband stole it. It's a solid device. Mini Protank II's looked great on it. Simple, inexpensive, single, bottom coil that you could rebuild later if it you want to try. Hubby also used his iClear 16b a lot on it. Said it tasted a little better with it, but I never found the additional taste to be worth the power drain and juice consumption of dual coils.
Another thought would be to try a 15 or 19 mm tank from IBTanked. I found that cartotanks offer great taste without rebuilding. Little bit of a learning curve on how to prime a carto, but once it's primed and the tank is filled, I find that there are less overall issues to deal with then with a clearo. Less leaking, gurgling and dry hits. The carto lasts longer then a coil this way, and you're only task for a while will be to top off the tank when needed. When the carto does die, its a slow death so you've got a lot of warning.
