I’ll try jungle watermelon instead of TPA, and drop the fa cantaloupe to 0.5. Do you know which brand Ruthless favors in mixing? I was beginning to think they use their own extract, but the scale of their production it must be branded concentrate.
Probably mostly cap and tpa. Maybe lo. Remember…big name companies often use those as well as FW. Atleast 2 years ago.
Ok I did a bit of research for you in the direction of acids.
Cantaloupe- no acid present
Strawberry- citric , secondary malic & tartaric
Watermelon- malic with trace of tartaric.
So knowing this you can accent your fruits to give them more zing. So I’d be adding say .75% each of citric & malic (tart & sour is just that, so if you have that do 1.5%) then a tiny dash of tartaric if you have it. 0.1%. I find matching the acids to the fruit a real benefit and does no harm unless you overload. Can’t hurt to try. Good luck.
