I like " Fett's spurs", as you hear less of the spurs, but more of the sound build into Fetts costume. I spoke to Matthew Wood a couple a weeks ago and had asked him about the sound, if they would eventually make it "public" or if he would have more info about it by any chance, he said he remembered that it was used in the SE in the ROTJ scenes, haven't had a chance yet to check out the movie again, so don't know if that info is accurate.
