I have used spitfires every year until last year when i went to the two blade rage. I was so impressed with the hole and blood trail and the fact that the buck only went 40 yards that i am using them again this year. However, there will also be spitfires on my quiver as well. I've always loved the way the spitfires fly and the damage they do. I only lost one deer with a spitfire and that was a bad shoulder shot at 37 yards. I would probably have lost that deer with any other broadheadas well.
