congrats: JediKnight2601 you revived the thread xD, gave us about another pages worth of posts.
Good for me because I did kind of want to post on this =p
What I personally would do is make use of your free hand... its almost like going short sword vs long sword. Since he has two blades he loses some of his previous abilities that you can exploit... Learn to control one of his swords.
(id go for the off-hand because more often then not I've seen them using the off hand more defensively, which I don't quite agree with mind you but I wont get into in-depth my philosophies here xD)
if you can control one if his sabers, you can make the other one useless, lets say for example you grab one of his arms after fending off one of the sabers, if you know how to pin his arm properly, his opportunity to attack vs yours is awkward, take full advantage.
keep fighting him eventually you will evolve to combat with your style
always look at your opponent, being faced with two blades seems very scary and difficult but it has its weaknesses like other styles.
And Always control the center!!!
