I'm also one of the "don't mix drinks very often" crowd, so I probably can't help you here. However, if you like the mojito flavor, you might keep a lookout around Halloween. Last year, Jones Soda rolled out a non-alcoholic mojito-flavored drink called
Monster Mojito Soda. It was actually one of the better tasting beverages in the
Halloween 2006 collection.
They sometimes repeat flavors for the Halloween releases, so I wouldn't be surprised to see it pop up again.
Now, back to your original question, perhaps someone a little more knowledgeable can chime in!
