i make my own and prefer 50/50, i went through a stage with high or almost all vg and the downsides that ive noticed are
i was using 3x more flav,
waiting for juice to steep and take on all flav's,
high vg ratio on high power mods spit more giving you a hot vape or scorched tongue/throat,
all glass and mirrors collect the vapour from the vg
& just something else i wanna mention is i've been using 50/50 for a long time now and yesterday just for giggles i thought i'd fill my rda with straight vg, well i never noticed this before when using high vg but it gave me a serious kick in the throat for a good few pulls, anyone else had this?
