Hayabusa vs. Sion- Sword fight

Ryu Hayabusa vs. Darth Sion. Both combatants can only use there respective swords (Ryu has Mk. II saber, Sion has lightsaber.) only. No force and no magic abilities.

Hayabusa is the better swordsman hands down. He is probably faster eventhough the force naturally grants Sion a degree of super speed.

Question is...how long can Hayabusa stand against Sion because he won't be able to phisically put him down unless the Plasma Saber is actually able to chop his head off.

Sowrd? Wtf is a sowrd? Does Sion not have his invulnerability?

Ryu removes Sion's head.

Sion's actually very good with a saber, as that's where his combat expertise lies. His speed tho not as great as Ryu's as far as I can tell, is still good as all Jedi are capable of increasing it, especially saber specialists. Ryu will have trouble in this fight, I assure you.
