Samm, these guys are members of the mutual admiration society. They will back each other up regardless of how stupid either of them has been. Shane, frequently 'mis-remembers' events in order to maintain the luster upon his own ego. I can tell from the screenshot that you were, at one time, HO on Shane. Obviously, you pulled off and he chose to fire instead. You should have fired at him.
The problem is, when you're above an La7 and hot as you were, you can't rate fast enough out of his site window. Gravity holds you firmly within his view for as long as he needs. Plus, gravity aids him in rating his nose to track you as needed. This is one reason Shane uses the La7; it already has great rate ability, plus he can use that to advantage in HO.
Whether you beat him, or not, you will get the same response from him. He is not known for his sportsmanship, so you can't expect any of that from him. If he doesn't like what you are doing, tough. Make him suffer.
