The quiver angle is what it is, and it's for a good reason, and been tested now for more than 2 decades.
Why would you want your feathers sticking up and catching on everything you walked too close to?
Why would you want a quiver tied to your thigh like a gunslinger...you gonna quick draw something?
A quiver that rides high on your waist, and trails straight back is THE BEST way to carry your arrows, IMO, in a hip-quiver type design. A lot of bowquiver fans say they can navigate brush better with their bow quivers.....I would certainly challenge them anytime. This design minimizes your profile going through brush, minimizing the impact on your fletching. It also stays horizontal when you squat or kneel down upon sighting game, and not sticking up like other designs, flagging your presence. Couple that with a quiver caddy, which is still the only "hang-on" type quiver out there....and it is the easiest, bar-none, quiver to remove and put back on should you get tangled, or need to do some crawling, or just settup to call elk or rattle deer. And it hangs easily in a treestand right next to you making a second arrow a quick and easy process.
I don't want to try to talk the bow quiver guys or any other type quiver fans out of their choices....but unless you give this option a try, you have'nt tried them all (like most of us do) or tried the best option on your hip. That's just me, but I've used this from above the artic circle to Texas, and crawled through every kind of brush thicket and wore every type of pack....it just works best for me. And not just me, but there are a few others.
Anyway, I know Tim has done a great job here of building a trad-type arrow quiver, built on common sense solutions, and not just fashion....that should appeal to some guys, I think.
Pat....to answer you questions about the frame, when I was building the quiver caddy's I tried aluminum and it just does'nt hold up like steel. The steel frame is really not much heavier, and you will NEVER wear it out hunting. It will last your life, I'm sure of it.
Also, on price....Tim reports to me that the quiver alone will cost 95.00 shipped; the quiver caddy alone is 45.00 shipped (same as it's been for some years now), and together they will be 135.00. A real bargain, when you consider how much work goes into this and how well made it is. Hope that helps answer some questions.
