One other lens that I'd add to your short list above is the Contax 350/4 Tele-Apotesar. True, the image quality is a step down in quality but the faster aperture vs. the 5.6 Superachromat is appealing, as is its close focusing capability.
Brad, if you are able to change your digital sensor interphase to Contax 645, you can also use the tele-apotessar T* 4.0/350 autofocus lens as well as all of the Hasselblad Superachromat wether they have leaf shutter built in or not. What I like about the Contax 645 camera is its light weight with a waist level finder and it has the best mirror vibration dampen. The reduction in vibration whether instantaneous or cumulative is essential to long telephoto lens.
Also the Contax 645 system offer the closest focusing distance lenses along with only the Hasselblad V system for the 200 series. This optical feature is great for portrait works and macro work in the field with the additional tele-converter unit. Thus, your system is now more flexible in your dynamic shooting.
