Can any one offer suggestions and tips for corner beading?

I’m working with the stuff for the first time ever. It’s not bad. I just get frustrated because, in the end, it doesn’t look as professional as I’d like. But I have more to go, so I’ll just keep practicing.

Now, let’s say I have to go up 6 feet, then over 1 foot, then down 6 feet. Rather than cutting 45’s at the corners, can I just bend the metal to go around the corner? I It seems to me that it would be a lot easier, and a lot cleaner doing it that way. Thoughts on that?

I also learned that gluing the things to the corner is a whole lot cleaner than screwing them in. I’m having a hard time getting all my screws counter sunk, for various reasons, so I think I’ll just go with gorilla glue from now on. What is the down side to that, other than if anyone wants to go in after me they’ll have to rip the shit out of the corners?
