I have the 9, 7, 7Si, 800SI and 600Si, the 9 is very good, wildlife, landscapes, action, I plan on using to shoot the solar eclipse this summer, top shutter speed of 1/12000 second will come in handy. The 7 is my second body, but I like the 600 classic and 800SI for travel, the 800 has the most powerful pop up flash of any 35mm. For sports the 9000, with motor drive 7 FPS, runs on AA batteries, but has slower top shutter speed. I just shot some Rugby with the 9000 using the 100 foot back, problem is that I will some frames cutting the film to fit 36 exp reels, don't know of lab that runs a black and white versiamat.
