Wow, I am an idiot. I had my nock point a little too low and also moved my pivot arm to the center whole and the rest to the hole away from the archer like you guys have it. Took it out and got a PERFECT paper tear out too 20 feet (that' s as far as I paper shot it). Went out and got what appeared to be GREAT arrow flight with my field points. Wanted to see how it shot with my 100 grain muzzy' s. No difference in the groups or flight of the arrow. I am amazed. In 13 plus years of bowhunting I have never felt so confident with fixed blade heads (I have almost allways shot mechanicals). Look out Mr. Colorado Bull. I will be headed out Sep. 4th. with my Muzzy ZE. Thanks a lot for the help guys.
