Flavours vary based on taste and preference. The consistency of a flavour is very important in it's usage. As a buying customer, you would have a certain taste of flavour you are expecting from the seller. If the taste is not the usual taste or it is not the taste you were expecting, that is the end of the transaction.
I am use to flavours and I change them at will but I stick to the familiar ones because there are flavours that have a different taste, they are not the usual flavour I do use.
You know the flavours are really important because they give taste to what you are doing. The better the flavour, the better the taste.
