RE: two piece quiver or detachable????
I like the 2pc. quiver & would never change. I have used them for over 12 years & have no plans on using anything else.
I hunt from tree stands, stalk, still hunt, and hunt from a blind & this type of quiver works best for me. It is also a little quieter than a removable model & the Mathews model is the cream of the crop when it comes to 2pc quivers. Of course you must decide yourself. I know people who can not shoot good with a quiver attached & so they remove them. I think bow length plays into that a bit since they like short bows & I use bows that are at least 38" or longer which help stabilize the affect of the quiver in my opinion.
Good luck how ever you go!
