Thanks all for the supply suggestions. I guess I'll buy the strongest NIC in a 100% VG base, get some plain PG and VG, and just mix from scratch using the calculators. I thought I could simplify things if the base was pre mixed fairly close to my final goal. But from the various posts, it seems logical that I'll have far more flexibility if I just get all the base ingredients separately. THANKS!
100mg nic is definitely the way to go. I like to make nic base first at 8mg or 10mg. Then use the base to make juice. You have to be extra careful working with 100mg, and I don't want to be bothered adding small quantities of scary stuff while I'm mixing juice.
