I like that idea. I just saw a still from something that was supposed to be a prequel to Sparticus. Guy was holding a monsterous long sword. What's up with that? I thought a gladiator were supposed to be waving around a gladious, or something like that. All I can say about that toad sticker is that it was a bit short for a Claymore.
Not too far off, but what I have is longer in proportion, and distinctly pointed. There's a brief review of "Spartacus: Gods of the Arena" on D2 of Friday's (1-21-2011) WSJ. Does it look at all plausible?
