I am torn, I know either one will kill a deer, period. However I am not sure which one I want to use. I like the 4 blade cut of the mx-4 and i like that they come with practice blades. However I have practice blades for the spitfires also, and I like the 1 1/2 cut of the spitfire. I am not worried about flight characteristics because they both fly great from my setup. Its almost like just close my eyes and pick one. So let me know what you suggest and why.

Also if you suggest another broadhead please tell me why.
