Sword fights are notoriously hard to capture in comic form. What are the best lightsaber duels you've found in Star Wars comics? The best I've come across so far are those in the Star Wars manga adaptions...they have power and energy lacking in a lot of others. Jan Duursema draws a lot of duels, but her pictures can seem quite static and posed. I think Mace vs Sora Bulq is he most effective one. While only one participant was using a lightsaber, the Luke vs Lumiya fight had an epic quality and actual choreography that make it the most cinematic.
I'll agree with Luke vs. Lumiya, but I feel that their first duel was superior. Mostly, just the surprise factor of seeing Luke lose.
