What Strawberry and Raspberry concentrates do you have? You could mix them with that but you'd need to know what brand you're using as percentages vary.
I've got a good Orange one I make for a pal
Flavour Art Blood Orange - 4%
Inawera Pineapple - 2%
Inawera Menthol - 2%
WS23 - 1%
Also do a variation for someone else that wanted more Orange in it. Add 2% of Inawera Shisha Orange and 1% TFA Pineapple to the mix above.
