I stopped at a local vape shop for the first time this weekend and was going to get a house chocolate mint juice and the guy saw my arctic tank and said it would be too rough on an arctic and gave me other options instead. I'm relatively new to gaping but I've been vaping 50/50 to max vg from mbv fine. So he showed me other juices and I got Midas cinnamon chill which is 40vg and this is the first vape I've had that I felt was rough. Almost like a gag reflex that makes me immediately need to blow out not sure what that is either. But main question is do I need to buy "premium liquids" on my arctic or are the house blends fine and he was just trying to sell me more expensive juice?
