Thanks two4hooking for sharing you post. For you, it appears you have a solution. Clearly, when one put's their mind to it anything can pretty much be made to work. That doesn't mean it's the best solution for all.
Strapping a quiver, as you have would not work for me at all given where and how I hunt along with the style of pack I use. I prefer a low profile pack for ducking under trees, etc so my Bison Gear - The Lost River is perfect for my purposes. A great pack for archer's that many use here
http://www.bisongearonline.com/page/page/2957669.htm The ease of a bow quiver for me is the most efficient when I consider all things.
If transporting many arrows for overnighters, etc I could see attaching a quiver like you have but I use an architectural document tube for that, which for me is much more practical given the terrain and living in a rainforest.
Hope your season progresses well for you!
