Haha exactly my thoughts..

If im too fatigued to make an accurate shot, im not taking it. Most of the time i like to wait to draw untill i have a shot or the buck is just about to walk in the lane. I know sometimes it doesnt always work out like that and you have to hold your bow. I sometimes practice holding back for an extended amount of time, then shooting i think it helps build endurance.

With all the new bow technology its gettin easier and easier to hold back longer and still shoot accurately
