I would take TWO cameras, the digital is OK, but still no where near the quality of film and if one camera goes bad on you! Denny is right about the dust, it will wreak havoc on electronics, keep your cameras in the heavy ziplock bags they have at backpacker stores. Get a copy of the "Perfect Shot" book and study it, it is written for gun hunters, but the anatomy photos is the useful part. Personally, I wouldn't take three different kinds of arrows, it just makes for more opportunities for things to go wrong, one bow with a back up and one kind of arrows that can be used in either one is the way to go imo.
