Without reading the comments, I first came up with 2-1-2-3-4-5-4, then decided that I really liked 1-2-3-1-2-3-2 much better. My reasoning is that while doing a thumb-under with the second finger is probably the easiest crossover to do smoothly, thumb-undering the third is not really that much worse, and for me, the added bonus of not having to use my fourth and fifth fingers more than makes up for it.
The last two fingers are are by far the weakest ones of the five, and while this shouldn't prove any problem for an accomplished keyboardist, they are still more difficult to do a trill smoothly with, and not something I would trust to my out-of-practice fingers.
