Taz, I have had a fixed blade broadhead sail in the past but.......that was while I was checking each broadhead and arrow. I have not had any fixed blades(Muzzy) sail on me while hunting. Honestly, ,my fixed blades shoot right with my field points. I can shoot both without moving my sight pins, and hold the pin exactly in the same spot with either. I don' t have to worry about the blades opening at any angle or opening upon impact because my fixed blades are already open.
Try shooting 30 - 40 yards with them on a windy day and tell me they hit exactly like your field points every time!
That happens to be the main reason I prefer mechanicals over fixed blade heads! It has nothing whatsoever to do with tuning my bow! I guarantee you my bow is as well tuned as anyone elses bow here. I use to limit my hunting shots inside twenty yards on windy days. Now with the decent mechs on the market I' ve gone back to my forty yard max regardless of the wind.
Are there stories of mishaps with mech heads? Sure! Are there stories of mishaps with fixed blades?? Darn straight!
Shoot what you want and let your own track record speak for itself!
