I've long been of the opinion that, for the most part, Sin/Dex has lost out on art duties while other, less-deserving strips, recieved the art goodies (Wilson, Walker & Jock on Tor Cyan being a perfect example). Tor Cyan was quite weak. A shame, as Mercy Heights was pretty damned good and it'd have been nice to have the payoff of the character's genetic infantry heritage be handled in a more interesting way once he got his own series. Am I the only one wanting Mercy Heights to have something of a return? It wasn't an all-time classic, but it was good, solidly written and often had great art.
Bec & Kawl isn't something I encountered, it occurred entirely during my period of foolish unfaithfullness to Tharg. Is it worth tracking down the trade? What does it remind you of? I can forgive early episodes being weak if it gets better. Even if it is mostly a humour strip. I liked "Robo-Hunter", "I Was a Teenage Tax Consultant" and "Balls Brothers", so there's a precedent for me enjoying the humour strips in Twoth.
