Love mine. I decided to try one last year on my guardian and put another on my general this year. IMO it has everything I want in an arrow rest. Built like a tank too.
I prefer the side load over the top load becauseI like to move around in the early season down here in Florida using a fawn bleat for doesandI can have an arrow nocked and carry my bow hanging downby my side,up-side-down, with out worrying about the arrow falling off.
I question acheiving center shot. I've had to cut the rests inner arm off to acheive center shot on several model/make bows. I can't imagine how that rest acheives it on some bows.
It sits behind the riser so the arm never contacts the riser. It lands on the bottom of the "hood".
