With me it depends on what class I play, for sociable PC's, 1/2 elves, front line fighters are Dwarves, ninja like PC's I use halflings or gnomes, spell casters are either elves or humans (or a "lesser dragon" if allowed), archerer's would be elf, and things like monks are half elves or humans. I've played as a lot, so I know a lot of the tweaks for the characters I play as.
