I feel like you can't go wrong with a U-lock around the frame and rear wheel and something sturdy. Look up some of the post around here where people try to explain Sheldons method. It takes three pages and diagrams and some people still don't get it.

I think a crook is more likly to see you have a good lock on afixed to a permanent object and move to the bike beside you that he can lift over the pole that ruin your frame trying to pry the lock off. I can imagine a person looking at your bike(with Sheldon's method) and thinking someone screwed up and bending either the rear trianlge or rear wheel(and I'm not sure how difficult it is to saw througha wheel but I imagine its easier than a kriptonite u-lock).
