What are your opinions on breathing liquids??
No need to vent unless you can taste alcohol IMO.
Can single flavours be used at a higher % to gain a full on strong taste and still be smooth, for example using FA forest fruits at 6% or would you still only mix it at 2%??
Some flavors are harsh at higher %'s, but some aren't.
Your gonna have to experiment with each flavor to find the point they become harsh and then back down a little.
Like Huck I've never gone above 3% with any FA Fruits.
But it's probably better if you try samples of your fruits stand alone first, then you can get a base line for each flavor, & keep notes.
Mix small testers like 10ml in a 15ml bottle, that way you can add incremental 0.5% amounts to fine tune.
Everybody pretty much has to learn their flavors first, before making any fancy recipes.
Can also use recipes posted here & elsewhere and make adjustments after learning your preferences.
It can be time consuming but patience will pay greater dividends in the long run.
Don't be afraid to try out other brands like INW, CAP, TFA, FW, etc.
Each brand has some really good flavors.
I started with FW, then TFA, then FA, then CAP, and INW last.
Along with a few others along the way like Hangsen, DIYFS, NF, LA, & Flavorah.
