I spent some time talking to Malachi today, and with his assistance I was finally able to reproduce the problem he’s having. It would appear that the timing necessary to successfully do two consecutive aerial kicks is just natural for me, which is why I couldn’t reproduce it before, but I’ve got it now.
After a little more exploration of the timing, and combining the idea that Aimee came up with for a HUD that displays which keys you are using at the time, I thought I’d throw together some quick little video captures of what the timing on the Taketori is like.
In these videos, you will notice that I can hit W very fast, and while the W slash is still "in progress", I can simply press and hold the next attack key and wait for it to fire off when the W slash is done. It’s possible to chain attacks like this for very long combos if desired, and you can still break the chain to go into block at any time.
Sorry about the poor video quality and choppiness, I still don’t really know how to capture video from Second Life. I did slow them down intentionally (and some browsers play them even slower than that), so if you’ve just come across my site randomly and aren’t already using a C:SI sword, please don’t think they are actually this slow 
I’m still trying to figure out the best way to resolve Malachi’s issue, as I think it has implications for some of the other issues that have been reported, but I think it also helps if people know what to expect with the Taketori, and hopefully the above videos will help to demonstrate that.

I should probably also note that just because you *can* use the timing demonstrated in the above vidcaps, it doesn’t mean that you have to. I demonstrated the extreme to illustrate one way of using the sword, but you can also use it like pretty much any of the other swords, with the exception that it doesn’t support “auto-combo” or “stacking” - where you press multiple keys *at the same time* and the sword does each in turn.
I’m button mashy enough that I just figure, Press an attack key over and over until it triggers the movement, and switch to another is a good enough for me sort of action. I’m still working on precise timing and key control.
I think the keyboard thing would be a nice thing to get out as a training tool and a debugger. Perhaps you could even link it into a practice mode in the sword that changed the keys colours when the sword is accepting input, but I don’t know how such a script might be synced.
Just an insomniac thought.
Keep up the great work.
