Need advise from experienced vapor's please.

Subohming should be a last resort, not a first recommendation. There's a lot of issues that go with subohming, and it's the most expensive way to vape. It's not for novices.

My recommendation would be [...] an Aspire nautilus tank.

Can the Nautilus handle high power, though? You'll note that I said "if you want to use high wattage, then [...]". OP is experiencing issues with his/her Kanger Protanks, and I figured the Nautilus was right about on par with those, as far as performance. Is that wrong? I haven't actually used a Nautilus myself, although I am familiar with the Protank series (mini PT3) and other tanks that use the same coil (Evod2) and I like them right around 10 watts/4.2 volts.
