Have you tried any of OoO's that really stand out to you?
I haven't picked up any cereals, I have about 10 of their flavors and have mixed 5 or 6 of them. When I ordered I had 30ml's of louie's loops and cereal killa mixed up already so I grabbed other flavors. Fruity pebbles is in my next order from them though.
Rainbow sherbet (unicorn puke) is fantastic, steeping lime sorbet but smells awesome. Others i had too much flavoring so I can't say yet or like plum I think will be great but I used too much sweetener, didn't know it's strength but I will mix it again this weekend with little to none because I think they mix plum sweet right out of the bottle.
From what I hear a few juice companies use their mix and sell it retail. Tell them which flavor at what percentages, email logo jpeg and they mail you hundreds of bottles mixed up and ready to sell as your own.
Their sweetener is not em or sucralose, I am getting better results with it than I ever did with em or suc.
The milk undertone is just that, better milk flavor than I have gotten blending sweet cream and Bavarian cream or cap vc.
