Eclipse are my favorite 2 blade heads. Probably because I have used them for so long and have had such great success with them, that I feel no reason to change. They give me confidence, and I am beginning to realize that confidence in hunting is much more important than many people think.
With a KME sharpener or even just a file, I can get them extremely sharp. I once shot a huge bull Eland in Namibia with a 55lb. bow and an eclipse head. I aimed straight up the leg on the broadside bull (vitals in African animals lie forward of north american species). The arrow blew through the leg, went through both lungs and stopped just under the hide on the other side of the bull. He went 40 yards and was done. That night, I touched up that same head and used it to kill a warthog the next day. Great heads.
