I don't know if anyone is going to read this but some of you folks may want to know...
I have 10mg 100% VG and 12mg 50/50. I can't mix these two to anything lower than 10mg or higher than 12mg. The difference between 10mg and 12mg is minimal. The choice between 50% VG or a higher percentage of VG is probably the bigger consideration for most folks. Thank you very much, carry on...
