To be completely honest, I don't know of a single method that I wholeheartedly endorse. I have done it a number of ways myself and have never been fully satisfied with any of them. I show students what I am doing at the moment, but I suggest they investigate a variety of methods online and choose whichever they prefer. I don't care which method they use, as long as it is safe and minimizes the critical risk of line entanglement.
For me, the biggest problem I see with the methods shown in most videos is they are always showing it done with small spools. When I am sending up a bag, it is most often from depths like 200 feet, and my students have to demonstrate that as well. Things are different when you are using a reel with that much line on it.
