McNally is a Nikon guy, but if you know anything at all about the Canon lineup you'll realize that Canon has almost identical equipment under slightly different names: Nikon: "speedlight," Canon: "speedlite." That's how much difference there is between the company's flash equipment. For instance, Nikon has the SU-800 infrared wireless controller. Canon has the ST-E3. Both do essentially the same thing. In his books, McNally concentrates on the principles of flash. Most of the equipment he mentions is Nikon stuff, but he also gets into heavy studio equipment like pack and head and monolights when that's appropriate. Besides that, McNally has a terrific sense of humor, and it's a real pleasure to read his stuff. Sometimes I'm ROTFL.
So far, the Odin has performed flawlessly for me. The range of the thing is astonishing, and it doesn't have quirks like the Pocket Wizard, which requires a specific turn-on sequence if it's to work at all, and sometimes fails even when you follow the sequence. I don't have a Mitros, though I've thought about it. I have two Nikon SB-910's, an SB-700, and an SB-600, a collection that gets the job done. One of the things I like about the Odin is that the way its controller works is close to the way the SU-800 works.
Since I don't charge for the shoots I do in and around the retirement community where I spend winters, I don't have to worry about anybody telling me what they think the result should be. I used flashbulbs in the fifties and barely competent strobes in the sixties. Both were a pain in the rear. Then I went to pure available light for a long time. But this new stuff is a barrel of fun.
