Hi Mate, so sorry I missed this comment until now. I use drippers to test flavours. Generally the same dripper which I have multiple of, which are the CLT Infinite 2+, running dual coils at around 0.4-0.6ohm. I would highly recommend going to RDA's for flavour testing. Perhaps look at getting a velocity clone, plume veil clone (though these are old school now I am told), or another 22mm RDA with a standard drip tip size. Avoid chuff caps as that is a pretty good indication of a cloud chasing RDA for the most part.
