Suggestions for first attempts at menthol tobacco?

[Spectre13]

Looking forward to DIY. I'm tired of spending the money on premade which turn out terrible - as well as the long wait for processing and other delays. I figure I can make my own terrible juices and save money.

I like mentholated sweet, caramel tobacco.
The tobacco flavorings I have on the way are
Camt (FA)
Royal (FA)
Red Oak (TFA)
Black Honey (TFA)
RY4 Asian (TFA)

I also have Koolada (TPA), Menthol (66% menthol 34% PGA by TPA) VW & EM (10%PG)

I see a few of those tobacco juices not only can stand on their own but some are used as an ADV by some. Royal sounds the most promising based on the description & reviews. (I know individual tastes vary though.)
I'm figuring to try each bacco flavor alone in my base (70/30 PG/VG 18mg) and 'simply' add menthol and/or Koolada then try each one after steeping a few days.
For example as the starting point:
My test samples will be 5ml (or should I start with 10ml?)
FA Juices - 1% / TFA 5%
Menthol - 3%
Koolada?
Then adjust from there.
Does this sound ok? And should I use Koolada in place of menthol or just to enhance the menthol or not at all?
Any heads up and suggestions would be greatly appreciated.

Start REALLY low on Menthol. I would say lower than 3%. Too much will kill it... you can always add more if you need to.

Koolada is not a "replacement" for menthol. The koolada will give you a cooling sensation in your mouth/lips etc. The menthol will give you a nice throat hit. Try the Koolada on it's own though so you see what it does for you. I use both together quite a bit.

I suggest mix small batch at first 5ml. Add your tabacco flavor at around 8% get some vannillin or cotton candy at 5% for sweeter. When it starts getting to were you like it add other flavors as you like. And menthol add about 1% it's real strong.
Google breaktru for a calculator for mixing. I get all my DIY stuff from Wizardlabs.us or myfreedomsmokes.com
I like useing PG at 30% VG at 70% nicotine at 18. Keep records on each mix with notes.

You should try out RY4 and DOUBLE RY4 I love them for tabacco flavor. I also been adding a little TFA - Tobacco Blend adds a little something special to the mix.

Brown sugar is also supposed to compliment tobaccos well. Some people even add a drop of vinegar. As far as menthol goes, if I add any at all, I literally add one drop. Mind you, I make small batches as I have not perfected my juices, so I want to make sure it's something I'll like. So it's 1 drop of menthol per 5 ML. Even that is strong and I sit whatever juice it is, out with the cap off for a little bit so it can air out. Otherwise, I get a really strong menthol accompanied w/ an alcohol taste that I find unpleasant.
