Interesting, and thanks for trying my version. I live in tropical Asia and use limes from my garden. They may be a tad sweeter than cooler climes' citrus. But for sure I used authentic Galliano.
Another website has the Vic Bergeron Mai Tai as without the extra syrup (just the divine orgeat) and with a healthy dose of each a white rum and a (floated at the end) dark rum. Well, how do these issues get resolved? I have no idea, but I will say that when you don't have TWO syrups (the orgeat is sufficient) and when you float the dark rum, you really do end up with a marvelously balanced mai tai.
