I understand ..... Yeah, for myself, I personally like strong flavors such as cinnamon or pineapple with sweetness added... There are lots of flavors that I can barely taste no matter how much flavor concentrate I add to my juice....... The stronger the flavoring then the less of it I need to add to my juices and then the farther the flavoring will stretch...... With cinnaom for example, I only have to add about 8% flavoring to my juice in order to get a nice strong flavored juice. But with some flavors like banana and most custards then I have to add anywhere from 15 to 25% flavoring in order to get a strong enough flavor to actually taste.
Menthol's, and mints are also very strong flavorings and do not require much to be added to a juice in order to get strong flavor... Unfortunately, I do not care much for menthol, or at least I didn't when I was younger.... I may have to give menthol flavoring a try though because it will stretch a long way.
Sure wish you could make your own juice there in Sri Lanka
