My favourites in order are:
Choc + Banana
Choc + Strawberry
Choc + Orange
Strawberry + Vanilla
Just Orange is ok sometimes ... but other times I just don't like it.
I don't like Strawberry solo at all .. has a funny kick to it which is tempered by the Vanilla.
I don't recommend Banana + Orange + Strawberry.
I thought it might be an ok tropical kind of flavour - turned out a vile ultra fake bubble gum.
