Man don't beat ur self up about it. You will get another go around. I have only killed 3 deer with my bow in 8 years of hunting with it.2 of those deer were this year, needless to say I have made my fair share of mistakes, as has everyone that hunts anything. Can't be perfect alll the time.

and yea the Whisker biscuit should resolve that issue of yours but i dont think that would be a reason to go switching your set up and everything.
