Bandon takes this, it would be a great show case of the staff from both parties.
But I think Bandons TK is pretty good, granted im sure Sirak can defend against it.
But Bandon can be abit over his head, and Sirak seems to have a more calm demeanor when he fights, other than Bandons blood lust as a sith.
I think Sirak and Bandon might be even for but a few moments if Bandon can keep his head on.
Sirak was seen as the best Korriban had to offer to Kaans Brotherhood, which should accomidate his force abilities in some manner.
Darth Bandon was taught by Malak...one of most powerful Dark Lord of his time.
Hmmmm I would say Bandon in a very hard fight.
