The only bad day I ever had with a bow in my hand was when a cable broke at 3/4 draw on an old Bear Polar LTD that I had many years ago. Oh yeah, I've had days that I couldn't group as well as other days but I never let it get to me. As far as groups go, It's always the first arrow that counts anyway. When you're in a hunting situation you're probably not going to shoot a group since the hunt will be almost over after the first shot.......lol. I usually shoot I arrow each at 4 different targets and it gets me out of the pressure of trying to group all the time. Different strokes for different folks I guess.
