What clearomizers/cartomizers go well (without any flow and with good taste) with ego-C?

[Roma]

I am curious about clearomizers and cartomizers. Are there any liquids that do not flow, taste well and long last as well as compatible without any adapter/or with adapter on battery ego-C 650 mah?
Liquids I prefer VG based , maybe 50%/50% VG/PG...
