I don't use my main gear for trying flavours. My system is like this
Get new flavour and smell if you don't like the smell you won't Vape it.
Put a couple of drops in a tablespoon of water and taste it. Flavour is very similar to the muted taste of vapour.
Use a dripper of sorts to try if you like it keep trying it over a couple of days
If I like it enough I put in a small tank and keep trying over a couple of days
If it's still in rotation I will give it a proper setup
I hate devoting or spending money on coils or cartos for something that got old quickly. With me there is always a honeymoon period for anything new. So it has to pass the three day test. If I am still using something regularly (eliquid or gear) after three days then it's a keeper.
