The best thing you can learn to do is to use the banshee bomb WHILE doing a backflip. I've watched a lot of your videos and you never use that trick, but I do it all the time to kill people behind me. You can literally shoot backwards with the banshee. No one expects it. It feels like sex when you pull it off.
