Just went back to whisker biscuit on one of my bows and will likely put one on a couple more bows soon. If you sit in a stand mostly and don't do much walking then I guess it don't matter but a few days ago I was stalking pigs in some nasty briars and having an arrow knocked that wouldn't come off the string or even move was great. I killed two whitetail from the ground at less than 20 yards this year so the folks that say a biscuit is loud maybe have deer with better ears than mine.
Mine was loud but still could kill deer with it. Guess the level of the sound is relative, I just don't like any at all.
QAD is pretty much fully contained and the arrow can't fall out of it either.
