Size? Well a small tip is fine, you don't need to drown the part. I am not sure what the sizes are exactly off the top of my head.
Basically, you do not want the smallest size, as small amounts of flux can dry out over a few days and any still in the tip may dry and clog it. (fixable with a little heat or a good soaking in alcohol) You also don't need the big sizes... Go with a size or two bigger than the smallest. About as big as a straight pin. (in fact, you can use a straight pin to seal the tip when not in use if you get the right size)
