It is your taste, only you will know what works best for you. Experiment with different PG/VG ratios. The juices I bought were at 70P/30V and I mixed at that level when I started. I'm more into flavor but wanted a little more cloud with the flavor so I tried 50/50, which didn't work for me. I currently mix at 65P/35V, and that works for me. Eventually I'll try 60P/40V. It all comes down to trying different things to find out what works for you.
