i normally use 8-12 mg juice. the TH is not all that strong, but i dont like the idea of increasing the nic just to get a better TH. and high nic is not really a TH to me, more like throat irritation. i tried 24mg and it was too much. i like the full, lung/chest hit. if i added pga would that be more of the high nic hit or the full type of hit? can 100 proof vodka be used instead? and generally how much is needed for 10ml of juice?
