recipes aren't static. tweaks that can be tried to your taste:

boysenberry - 3-4%
fuji apple - 2-3% (2% helps brighten the recipe, 3% adds a subtle apple note)
shisha strawb - 4-5% (5% makes it sit neck and neck with the boysenberry fighting for the main note, otherwise it's a little more layered)

super sweet - 0.5% - 2%, depending on how commercial you want this to taste. 1% is the "sweet spot", as it is a candy vape. 0% = flat recipe, can't replace it with TFA sweetner. CAP, JF, PUR or FW preferred
keep the cool anise bliss and marshmallow at the same percentages
