Well, hypothetically, is the person holding the gun to your head only asking you to try, or to land the trick? If we just have to attempt one, I'm going with the ceiling tap because I know I won't make it, but I'll just throw a lincoln loop (which is easy), and make it look like I tried. Any attempt on that rainbow is gonna be sketchy as hell, at least for me. But if we absolutely HAVE to land it, I have a way better chance at the rainbow.
