I would love to be a one flavor vaper but I've just not found that right flavor thus far. I know what I don't like, I don't like floral tasting liquids, and I think I should know what I would like (things like spices, or very robust flavors) but as of yet, I've not found any that I could call my final liquid to vape with.
I'm also starting to believe that vape B&M stores sample 0 nicotine liquids and then when I buy them and get them into my own
tank the flavor isn't nearly as appealing as it was in the store, that's not helping to find that perfect preferred liquid that I'd like to find and quit all the buying of liquids that turn out to be not so great when I get them into my own tank. Now, I'm pretty sure that not all B&M stores sample 0 nic liquids but I'm pretty sure that some that I've visited do that and of course maybe there is no flavor change from adding nicotine, I just can't be certain other than to say that there seems to be no reason that a flavor should change drastically between their tank and a freshly washed tank with new coil at home.
Most recently I found Space Jam's "Pluto" which in the store tasted like bubble gum and honeydew melons, but once I put it in my own clean tank with new coil I only got another liquid that has a lot of floral flavor to me.
