Looks like ball heads are the way to go! Good to know. Wheatfield, I'm intrigued by the Feisol products, they are priced very well, seem to be within spec, and I was able to find a small dealer in Canada:

The Arca-Swiss and RRS look very nice indeed, but are probably out of my price range at the moment...which is also why I'm shooting with a 500/4.5 SMC Takumar instead of something a little more user friendly.
I'm really looking forward to getting my big lens on the monopod...I've had it for over a year and only had the opportunity to use it handheld.
Next question...SR with a monopod or not?
