Monoblocs, speedlights, etc

On friday we messed around with the monoblocs and sppedlights to create differentlighting effects. I found the monoblocs really easy to set up and control, easier than the studio flashes for some reason. Even easier than the monoblocs, were the speedlights. They are small and convenient, although they don't emit enough power required for studio work, they are really handy to use on location. We had trouble getting rear curtain sync to work on the 40D but after a but a bit of googling ifound that it won't work with a speedlight attatched.
