I just ordered some Vixen Vapors DIY RY4, some 24mg PG/VG, and plain PG/VG. My question is #1 has anyone used their DIY mixes, and #2 what % should I add to the base? I plan on mixing the nic and base 50/50 (both 60/40 PG/VG) to get to 12mg, then I was going to start at 10% RY4 mix. Opinions? Recommendations?
