I will forward your comments to Dr. Schramm, but first let me clarify that he never referred to a fish that had "puked its bladder," as you put it. There's a huge difference between a fish with a simple enlarged air bladder, and one with a bladder that protrudes from the gullet.
A fish with an enlarged bladder may appear normal, but go belly-up when you try to release it. Fizzing allows a successful release in such a case.
And with respect for your opinion, fizzing is actually a simple procedure that anyone can master.
Regarding the laundry basket method, I have to admit that I had second thoughts about it when Dr. Schramm first described it to me several years ago. Like you, I wondered about keeping a laundry basket handy. My solution was to add weights to a milk crate--the kind you find in any department store. Just wire sections of heavy rebar to the outside, along the lip of the open side. You could probably do the same with a 5-gallon plastic bucket that was thoroughly perforated with a 1 1/2-inch hole saw bit to allow water flow.
