Razz heads up?

[ceegee]

I've read up a bunch on Razz in tournament play and 6 handed, but I'm lacking info on heads up play, and short handed play.
Does the idea that 8 low starting is still a good idea to start with, or do you want to risk a low showing with maybe a j in the hole with another low card, and hope to make a better hand? Some general tips would be helpful thanks =]
