I tried one when they first came out with the wheelie bow - if you load them down with gear the pack doesn't center itself well, and tends to try and crawl around you. The idea with the quiver attachment is nice, but as you're attaching a bracket and THEN the quiver, it sticks out a bit and flopped more than I cared for while walking. With short arrows I didn't have as much of a problem with the fletchings catching everything, but with long arrows I felt awkward. The original material was kind of loud, don't know how the new material is. I tried it for one run in the woods and wasn't impressed - so Cabela's got it back.
Of course, your opinion might be different.
I had an Arrowmaster for a bit, great quiver and very well thought out. I just found myself wanting to try something new, so I went to an on bow quiver this year. I tried a Catquiver once also, but didn't like that I couldn't have an odd broadhead in it and grab it easily without nicking myself - but I'm clumsy sometimes too. Also felt heavier than my Arrowmaster. Can't comment on a Dawgware.
If you want an enclosed, modified back/side quiver with a bit of storage you just can't beat the Arrowmaster in my book. Rod pretty much nailed it in the design. I'd keep my eyes peeled in the classifieds for a used one - they show up every now and then.
