How do you decide which ones are necessary? Because if I can get back from testing all of them it would be a dream! It really is time consuming!!!!
I was thinking maybe I should start with flavors I use the most to find the different nuances in different manufacturers flavors.
Fidola, I think it just depends on how specific/specialized one wants to get from a given flavor.
Some folks want very specific characteristics for a flavor. That citrus might need to be more "zest," than "juice," or "candy." Other folks may just want a general citrus note, and not really care what specific nuances it may contribute. (Also, if a person only has one or two choices, and they are vastly different... making a choice may be rather obvious.

)
I find, it is most useful
for me, when I have a very specific goal/recipe in mind. When I am trying to create that "fresh from the vegetable stand watermelon," and I have I have 11 potential watermelon concentrates to choose from, it can be worth the extra effort. Trying to recreate a clone of a commercial e-liquids is another time having additional knowledge of your concentrates can help save time.
When you
do invest the time for side-by-side comparisons; be sure to write lots of detailed notes for yourself. Learn from my mistakes.

I did a rather extensive watermelon comparison a couple of years ago; and thought I had it committed to memory (other than a few scant notes). I grew discouraged with my early recipe creations (not "real" enough), and needed to step away from it for a while. When I was finally ready to try again; I had forgotten almost everything, and will need to start start from scratch.
My final thought on single flavor comparisons:
I generally find these
most informative; when I have
previously determined what
my preferred percentage is.
This may add even more time to the process. But, I have found the results to be near worthless, when I am trying to compare unfamiliar flavors. I did this with my first batch of lemon concentrates. And, because I had no clue what percentage (for each concentrate)
I needed to be using; I was missing many of the subtleties, others said they were tasting. My comparison ended up being a waste of time.
Yup,hubs got the tattoos too. They're not sure at this time how many days he'll have to go.
Fran,
Wishing you and your husband, an uneventful
and successful treatment. You both are in my thoughts.
