I'm... well, pretty much all of those! First and foremost I'd say the Samurai is the most accurate for me, because I block a lot and wait for good opportunities to strike. Occasionally I find myself unable to help but pound those Jackals into the ground, so there's a touch of the Conan style... and I also have a habit of forgetting about the health bar. Then I notice it when I have the tiniest fraction of health left and have to finish the fight with absolute perfection to avoid death! Sometimes I get just a tad nostalgic for the more FPS-focused Red Steel 1, so I whip out the Sidewinder or the Johnnygun and relive the memories.
I also use every single special move as often as possible, but that's more for entertainment than for the cash--although that's certainly a welcome end result. I gotta say, you guys whipped up an awesome amount of moves to use, so I make sure to make the most of it.
