Welcome peteculmer, I've never ridden any of the bikes you've mentioned, but the Hanzo does not match the other two. The Hanzo is the bottom of the range Pearson bike, and I don't believe its double-butted, so its going to be heavier. Its also in a different price range to the other two. Maybe you meant the Pearson Touche?
As for handling punishment, kerbs, canal paths etc., I'd probably give my vote to the Cotic Roadrat, as the bikes are race and team tested, so that's a bonus.
