I like one occasionally. I'm also torn because if I'm serving one to a guest it's nice to have the cream floating on the spirit to let them stir it themselves, but if you do milk+cream premixed it is hard to get it to float. To drink it for myself I use milk equal to the combined spirit volume and add just a dash of cream, all stirred in the serving glass. It gets a bit sickly for my tastes with all cream or even half and half.
The trick is to experiment in the hope of getting it just right before you pass out!
