First, I have only been doing this for three weeks, but, I thought I'd share.
Disclaimer: My perceptions will probably change over time! It took almost two weeks for my mouth to "break in". In the beginning I think I/we have high expectation that the flavors will "pop". I have found that the flavors are much more subtle and require effort to identify. Hope this gets better over time.
Tips and Key learnings:
1. More than one way to skin a cat.
a. TIP: read Str8V8ping blog for Quick Tips for % flavor tasting.
b. TIP: add one or two drops of flavor to 2 Tbsp. of whipped cream, yogurt, etc. this will give you an idea of how a flavor tastes.
c. TIP: Mix up a batch(3ml) using the ejuice calculator, print a copy and take notes, notes, notes and more notes!
e. TIP: for amounts under .4ml I use drops. For amounts over .4ml I use a 1cc/ml syringe (check Amazon). Over 1 cc/ml use an appropriate size syringe. Consistency is the objective!
f. TIP: When mixing a batch shake well and try to let it air out(steep) at least 10min. per ml. This lets the flavors mix a bit before you start to vape.
g. TIP: The right equipment(carto) is very important! They say the preferred vaping range is between 5 - 8 watts. Using the PV Tuning(Tools) option of the ejuice calculator you can determine the correct ohms for your carto's. As you can see:
I need carto's with less than 2.8 ohms. Higher ohms creates hotter vapes and burns flavors and drains the carto at a blinding speed!
2. While testing a batch, don't over do it. Take slow "FlavorPuff's" and let carto cool down between hits. Remember to draw in while exhaling thru your nose or you will create excessive condensation on the battery post. If you are getting a burnt taste, you are probably overheating the vapor.
a. I mix up a couple of batches so I can alternate hits. Its hard to put them down in the beginning!
3. To much flavor (high %) can kill the flavor. Try a smaller % before giving up.
4. Mix single flavor batches to begin with. This will give you an idea of each flavors vaping taste. I generally start around 10% except for well documented flavors like cinnamon. Then move on to multi flavor mixes.
5. Always try to save a little bit of each batch so you can test it again in a couple of days/weeks. Flavors change over time.
As I said, I'm new to this but I'm hoping this might help others. Perhaps the veterans here will have additional tips.

1. Using the ejuice print out, check off each item as you go along. I tend to forget what I've added. Either Alzheimer's or interruptions.
d. TIP: When using drops, always use the same size dropper. I find the glass dropper to be a 20 drops per ml. Others will vary.
e. TIP: for amounts under .4ml I use drops. For amounts over .4ml I use a 1cc/ml syringe (check Amazon). Over 1 cc/ml use an appropriate size syringe. Consistency is the objective!
