I went shopping for a new quiver last year and I had my mind set on a 2pc quiver from Fuse.  I was all ready to walk into the bow shop and get one.  Went in and the one I wanted they had just sold the last one.  I know the guys at the bow shop and they would have ordered it for me but we got to talking about  quivers and what I wanted in a quiver.  I wanted one that was rock soild on a bow and would hold my arrows tight in place.  I had a Octane 2pc and while it was rock soild on the bow, the magnetic hood just did not hold the arrows tight.  So they guys showed me the quiver from Tight Spot.  I must say this quiver is awesome.  Holds arrows super tight and when its on the bow it is soild.  I did not know if I would like the fact that its a one piece and that you can remove it very easily and quickly.  But they convinced me it was the hunting bow to get and they were right.  This thing is awesome and I glad they talked me into it.  A little pricey but well worth it.

My choice in arrow quivers are: first choice - hip quiver. Second Choice - bow quiver. 

With the hip quiver, you can swivel it around and slip through brush easier and quieter.

Bow quivers can affect where your arrow hits, relative to your sight picture because as you remove arrows from the quiver it changes the balance and dynamics of the bow.

A back quiver would be my last choice and I would not hunt with one. Too noisy, too much movement to withdraw an arrow, and does not protect the broadheads.

I bought an Octane a few years ago so I could try to carry those frustrating rages using the magnetic hood in the quiver.  After finally giving up on the rages, I got tired of lugging around the added weight of the magnets in the hood, so last year I decided to start shopping around for a new quiver.  The only criteria I had was that the quiver be 1) lighter and 2) removable.  I like to remove the quiver when I am sitting in a ground blind.  I ended up with the Tight Spot and couldn't be happier!  It's light, removable, adjustable to the bow, AND you can adjust the tension used to hold the arrows in.  It also sits very close to the bow which greatly reduces off-balance torque (hence the name).

Thanks for the replies so far.  With two votes for the Tight Spot, I will definitely have to look in to it.  I might have to give both a hip quiver and a bow quiver a try to see what I like best in the field.
