RE: two piece quiver or detachable????
Another vote for a detachable. I had a two-piece Hoyt quiver on my Hoyt for years and all it did was add weight.
I discovered the new Kwikee quivers and their quality has really come around since I first remember my father and I using them 15 years ago. They fit snugly now, have small, cheap, universal brackets that can be mounted anywhere, and they've got enough versions to keep me happy. I don't know if you caught my past post, but I JB Welded a bracket to the Summit and it's positioned perfectly if I need to get another shot off.
Now I've got the ability to get a shot off during the walk in if need be, and I'm not waving all that multi-colored fletching around in the presence of a deer......best of both worlds.
