I didn't answer the poll because "it depends." It depends on the diver's personality/aptitude and how much he wants to or has the attention span to watch videos online and figure it out on his own versus have someone actually show him the ropes and give him immediate feedback. It may depend on the length of the hose, as there may be a difference in technique between a 40" hose and a 7-ft hose. I believe the best way to learn anything is a combination of study and live feedback. To learn something a bit more complicated, like the frog kick, you can watch videos, but it's no substitute for having someone critique you in person. Then watch some more videos, practice on your own, and go back for more in-person feedback, rinse and repeat. But back on the subject of donating the long hose, I recall finding it kind of awkward at first in Fundies class, but after a few hundred S-Drills I would think I have it down now. And yet, every now and then when we're doing S-Drills, I forget to untuck the hose, or when we turn to head for the exit the hose flops in front of my face because I forgot to move it behind my head. So, there may be some not-so-obvious (to every OW diver) things to learn about it (which may or may not come across in every video out there) if one wants to be prepared to do it in a real situation without making a mess of it. Lots of things about diving seem easy when considered in isolation, but when you're trying to do it all together it can help to get input from people who have been there before.
