I am going to fall on sword and embarrass myself in order to offer an opinion that may or may not be helpful. I went through the same issue, and I made it more complicated because I shoot Right and left handed interchangeably, so I wanted a quiver that does everything. I tried bow quivers, hip quivers, back quivers, Korean dongae quiver, etc. I really got excited when I saw O Leatherman's Latigo Silent Stalker side quiver and had him ready to start punching one out for me when I realized my budget was busted. Then I started looking sideways at my dad's old 1950's King back quiver that I had been trying to restore to use as a back quiver but some of the straps were dry rotted . Plus, an old rotator cuff tear combined with longer arrows proved out to be incompatible with a true back quiver. So I did the unthinkable to an heirloom.
I ended up reattaching the torn remnant of the main back strap as a simple loop over the center of the top opening, removed and the large exterior pocket, knife and file sheathes and keepers, then boldly cut a large long opening on the "short" side of the quiver, removing a piece of leather about 12 x 4 inches. I noticed that O Leatherman doesn't cut the lower end of the bottom opening square but rather a bit acute, which provides more coverage for the tips, so I did that. Then I re-used and re-located the straps that were still viable, got a very old 2" heavy leather belt that my waist outgrew a few years back and made that into the shoulder strap that I attached at the top at the loop made from the original main strap and at the bottom to a loop that runs across the bottom of the opening. I went to WalMart and bought a $9 set of "yoga Blocks", dense closed cell foam blocks, cut a piece to fit into the bottom of the quiver.
The end result is a side quiver that throws on quickly over one shoulder, will hold at least 15 arrows if I want, securely holds broadhead tips ,field tips and judos in place. The top of the quiver rides under my arm held against my body by my elbow with the bottom of the opening right under my draw hand when I am shooting, so I can grab a shaft about 2 inches from the tip, slide it back a few inches then up and forward across the string and side plate with very little motion, far less than with a back quiver. It easily slides back to ride a bit more vertically and around to the back when I'm walking . Like a Hill back quiver, the leather forms around the shafts so nothing moves in the quiver. It works equally well righty or lefty with no adjustment required, just moving the arrows so the fletched ends ride outside the shoulder strap. My dad had added some clips around the top opening of the original to keep shafts from moving around, but those turned out to be both unnecessary and counter-productive, as the clips grab the fletching when you try to draw the arrow out the bottom of the opening.
Like I said, this King leather is 60 years old and when it falls apart, I am going to get O Leatherman to make me a new one from scratch, as he will certainly improve both the quality and functionality. He has a great design and makes a top quality quiver for shooting at the range or silent stalking with the added benefits of being easy to hang on a hook or stub once you're in your blind.
