I like sparkling mead, but I did just have a friends mead that was borderline over-carb'd. To his credit it was his first mead, and 3 years old.
I find it much much easier to force carb mead that I want to sparkle, then bottle with a counter pressure filler, or just keep a keg tied up until all 5 gallons are gone (which is the boat I am in )
