So, have you thought about possibly doing something about the Trākata saber form? I know its not canon but i personally find it interesting. At the least I'd like to see what you have to say about it.
Here is the Wookiepedia page link: http://starwars.wikia.com/wiki/Trākata
I probably wont devote a thread to Trakata, seeing as how it isn't an "official", but I may as well share my thoughts on it. It's use seems impractical, which, if you think about it, makes it even more practical. It can confuse the enemy into thinking that you are giving up, which can lead to a sneak attack of sorts.
It may have vulnerability to an extremely aggressive opponent. You wouldn't have much of a down-time to apply it.
