I don't know of any other way to tie a figure of eight knot. But that video does illustrate the drawing through of the long length of leader that is my objection to the knot.I wonder what method you're using to tie the figure of eight that makes it harder to tie than a blood knot. Check out this method of tying it: http://dryflyexpert.blogspot.com/2013/08/the-strongest-knot.html Having seen those instructions and video, I adopted the figure of 8 and haven't looked back.
With regard to the reliability of blood knots they are the knot used for commercially tied knotted leaders which is practical evidence of their reliability and strength and good enough for me.
In my view Tangled is absolutely right (not many people say that) with what he says in the last two paragraphs of the preceding posting.
