I have the two piece Mathews quiver on my Switchback LD and all I can say it it was worth every penny. You absolutely cannot go wrong with the Mathews line of quivers....Top notch.
Built in Vibration dampeners, adjustable to any size arrow as well as two different foam inserts, one for fixed broad heads and one for mechanicals. They also offer it in two different sizes. I opted for the extended one as I'm shooting 31 1/2 inch arrows and with the extended quiver my arrows don't extend past my lower cam.
