It's final - my wife has vaped this for the last week and she really likes it - she even expressed some disappointment at having to switch back to the commercial liquid I was trying to get her a decent copy of when she got close to running out. So we won't be messing with this recipe any further.
It is an after dinner soft butter mints type flavor. The flavor is not a 100% spot-on perfect copy of the MEL liquid -- it's slightly different. It is perhaps a tiny bit richer in some ways and has a nice peppermint that you get on both inhale and exhale, yet not too strong in my wife's opinion. It is sweet from the Vanilla Swirl, but not overly sweet. My wife likes it better than the MEL juice she has been vaping exclusively for the last couple years.
It is good right out of the can - I've been sitting mixed bottles in a pot of hot (not boiling hot -- just hot) water for 20-30 min or so and shaking several times during that period. But the flavor really jumps out after a couple of days.
Credit/thanks goes to my wife for helping me taste-test this, the unknown poster of a similar recipe I started from, and to Bill's Magic Vapor for the inspiration and very helpful information on flavor testing/development. I got it where it is now and where my wife likes it on the 4th try.
(and accidentally discovered something very close to a tic-tac mint flavor along the way that I will work on more later) I hope to develop other recipes good enough to share here.
For the record I mean no disrespect to "M.E.L." by going after this flavor. They are easily and by far the best e-liquid vendor we have dealt with in over 3 years - good liquid and good people! It's just that with the $$$ I've put into DIY for my own vaping, it doesn't make a lot of sense to keep buying commercial e-liquid for my wife if we can mix her something she likes and make it ourselves (and customize it to our taste) a lot less expensively. I would definitely recommend M.E.L. to anybody not wanting to mess with DIY.
This recipe was developed at 60% VG / 40% PG.

I've also made it public at the ecigvape recipe site. I will most likely be switching to the ejuicemeup calculator very soon but will probably continue posting/publishing recipes I have good feedback on at ecigvape.
