DanFromRioRancho, rather than settle on just one juice flavor at first, it may be more beneficial if you have a bunch of contrasting flavors so you can switch around while you make the transition.
Vaping is not smoking: the only thing the two have in common is that both are nicotine delivery methods. So, if you only smoked one brand and configuration of cigarettes, that pattern almost certainly won't hold for vaping.
I've found that vaping is much more like pipe smoking. Back in the day, I'd usually have four or five different tobacco mixtures open that I'd rotate through from pipe to pipe during the day. My pipe tobacco cellar has easily 60 different mixtures in it. (Do I still smoke a pipe? Very seldom, maybe once every two or three months. But I'm hanging on to my cellar which I accumulated over many years -- some of those mixtures sealed in vacuum tins have become quite valuable and continue to rise in value.)
Similarly, I have about 35 different e-liquids. Much of the time I vape one of four different menthols (Dekang Triple Menthol, Gourmet Vapors Crystal Menthol double strength, Vaporrenu Menthol plus my own DIY), but I'll vary those throughout the day and evening with miscellaneous mint, fruit and soda pop flavors. Some flavors I reserve only for very special occasions, for example MadVape Key Lime Freeze, which is absolutely superlative with a good sippin' rum taken neat in a snifter. Certain chocolates are miracles when combined with single-malt Scotches, also taken neat or with a wee drappie of water. And so it goes . . .
Over the course of a single day and evening, I'll probably toke on eight to ten different flavors. Needless to say, I've acquired lots of hardware over the last couple of years!
