4 moths, no tripod, no good

One thing that you must also consider here is the lens being used. That 300mm IS prime that Loupey uses is one of the best, fastest lenses in the Canon arsenal. Trying to do the same things that Loupey does with a 100-400 L zoom (even with IS) will meet with dismal results. Using a non-IS lens would be bad too. In short....Don't do what Loupey does unless you've got the glass to handle it. Better to use a tripod if you don't have a great lens.

I'm such a fan of this lens that if something were to happen to it tomorrow morning, I would have bought a replacement 300mm f/4L IS tommow by noon

Don't tell anyone, but it's one of those super values that Canon still sells (like the 200mm f/2.8L, 85mm f/1.8, and 28mm f/1.8).

I've recently slimmed down my fanny pack even further: I keep the 2xTC mounted on one 36mm extension tube (not to use together but to keep from rattling around), 2 extra memory cards, and 1 spare battery. Of course the 30D with the 300mm is in my hands
