Theres a line I think you shouldn't cross vyse. I my self play around with swordy combat stuff in real life, and let me say a single blade gives 10x more control rather a duel double sabre combo. The single blade me would pwn the duel double sabre me

. Double sabres are okay. Duel sabres are okay. Duel-Double sabres in my opinon, arent okay. Its like cheating, you think it will be fun, but in the end it ruins the game play experience.
The reason most jedi only use 1 sabre is the movablity and control it offers.
Grevious had 4 sabres and it didnt help him at all. But its your decison.
EDIT: did you try my combo files let??
