When I started vaping, I started with an Eleaf 30w iStick and a Smok micro gdc and got a Nautilus shortly after. I think the Nautilus and the iStick is the perfect start since when I got the nautilus is when I put the cigs down. Although I was a 3 pack a day smoker, 24mg of nicotine was too much, and I almost quit vaping because of it. I did 18mg for a few weeks, then cut down to the 8-10mg range. I also like high vg juice. When I tried 50/50 juice, it was harsh to me. Made me think of trying to take one last pull off of a cig and catching some filter. Now, at least 65% vg but usually 80%+. I couldn't do tobacco flavors, they were just a poor substitute for a cig to me. Now, the fruit and dessert juice I love. Helps with the food cravings I get when I try to quit smoking. I smoked menthol smooth's, but I am not big on menthol vapes. For juice, my favorite vendor so far is VapeWild. Cheap, lots of flavors and lots of options. I need to order some premium stuff to try, but the cheap route has let me try a bunch of flavors out and get an idea what I like. I would suggest getting 2 sampler packs, pick the same flavors in each but go slightly vg strong on one and slightly pg heavy on the other. 60/40 on one and 40/60 on the other. This will let you see how the vg/pg changes the flavor and throat hit. From there, experiment and see what works for you. It takes some work to find the best blend for you, but it's worth it. And it's part of the fun.
