I just had too much wrapped up in arrows to let a rest dictate which ones I could and couldn't shoot.
SO to "fix" your problem, you chose to buy another rest, when in fact you could've bought new arrows for about the same price and done the same thing!
If the noise was such a factor, why is it that it took a deer to alert you to the noise? Was it not something that you had noticed before the deer alerted to the noise?
