Yes, VG will cut the flavor too, but you indicated you were mainly concerned with checking for the right nic.
I can send you some TV tobacco flavor, say 12 and 18 mg strength, to try out. PM your addy if you want it. (Alternately I could do it with TV atomic cinnicide, but it's a pretty strong flavor. TV tobacco may or may not be to your taste, but at least it should be vapable to see if the nic level is right for you.)
TastyVapor makes trying different strengths easy -- they sell nic liquid in a given flavor, you can choose all the way up to 48 mg strength of many flavors, then they also sell 0 mg nic doublers -- the same flavor. I buy 48 mg and doubler, so it's easy to do 24, 16, 12, 6, and 18 is just mixing 12 and 24 strengths.
