I've cut down my mixing and experimenting time significantly with an easy shortcut.
Instead of mixing my 36mg PG, no-nic PG and 35% VG to 12mg for each small 3 or 5ml experiment, I've pre-mixed 30ml of 12mg base with above ratios leaving room for 15% flavor.
Now i just measure out 85% base liquid and experiment with flavor. Adding + or - 5-10% flavor does make a huge difference to the base and all this allows me to make quickie small batches.
