Oh - the other thing - the best thing actually - and something I can totally recommend - purchase George Ledyard's DVD on the series. That will not only save a whole lot of time, but it will give you tons of information to work on and with.
Thanks for the recommendation, those sound like a great set. Right now I'm making notes so I can try and do some visualization while I'm laid up, but don't expect to get much more out of this than memorization of the big steps.
I think that having words for this stuff will help me remember them in the longer run. For instance, the defender movments in ASU kata #2 goes (I think), "waki gamae, watershed, left-yokomen, right-yokomen-to-win"... well, the last isn't really a yokomen but I don't know the name for it.
I'll put Ledyard sensei's DVD's higher up on my "aikido wish list"...
