" ……and its very accurate as well."

Rests are not accurate. A rest only holds the arrow. If the design of the rest capacitates reliable effectiveness, and the rest is properly adjusted, the rest is only part of several tuning aspects that assists in enabling accuracy.

" It is a very simple rest to tune." .....but!

1. " How many FPS you will lose is going to depend on how fat the arrow is and how much fletching is going through the biscuit."
2. " Carolina Archery Products website has both pictures and tips on how you can modify the biscuit to make it have very little resistance for the arrow."
3. " Essentially, you flatten the biscuit by cutting the bristles with a pair of scissors or even toenail clippers."
4. Rough arrows will be noisier than smooth arrows unless you take the time to wet-sand them so they are smooth.

" This is a true bowhunter' s rest , and I believe it does the job better than anything else out there."

" I routinely shoot mud and grass covered blunt-tipped arrows through this rest when it rains…." ????

" If anything this rest is even softer and quieter than when it was new."

In other words, the rest wears, and in doing so it is reasonable to believe that the supporting tension and height has changed; and those changes will affect nock height and flight.

Everyone to their own, especially if they are satisfied. However, I just cannot see how supporting a shaft on brush-bristles that wear, break, loose resistance, and " whack" the fletching, can be good.
