The Mini Protank II looks great on the VV v3. Also, the Aspire BDC - ETS looks good too, and I prefer the taste from that one. It's a glass tank as well. The Mini Protank 3 came out with dual coils as well, and I do believe that Kanger is going to or has released the Mini Aeortank, which I plan on getting myself.
For outside the clearo category, I recommend IBTanked carto tanks. They sell slim, 15mm tanks that look great on the on the VV v3. That's my husbands current set up. He started to get pretty unhappy with his Mini Protanks. I started buying juice with higher VG ratios and the Mini Protanks weren't wicking them properly. He was getting burnt hits. Plus, his favorite ADV is a coil slayer. Very dark and sweet, and he was going through a coil a day. The cartos in the carto tanks last him a lot longer, and he prefers the draw and the taste from them. IBTanked will ship to Canada as well I believe.
