This is definitely one of the most crowd-pleasing tricks ever created. People absolutely love it (for good reason, btw). It's definitely not the most complicated or difficult trick, but it does takes quite a bit of practice just to be consistent with landing it every time. Something that might help is actually looking at the trapeze from the side as you do the Eli Hops---you can see me doing it in the tutorial. It makes hitting the string easier than if you just keep the trapeze right in front of you.
