I am an old school bowquiver guy, that said I used a side quiver for about 5 seasons when I was shooting one piece bows. I preferred the Duiker over the larger safari tuff. Duiker is perfect for 4 arrows for me, I use 4 fletch and large feathers. The larger one has more capacity than I want and starts to become unwieldy for me. I changed out the hood foam to thicker so I could fully bury a big Snuffer, covered the nylon banding around the bottom arrow hole with moleskin, added a small, flat pouch for carrying license and a few very small items. The pouch on the bigger safari tuff ways felt like it made the quiver want to be top-heavy if I put much into it and make it feel like it wanted to flip over.
I found that I prefer to reinsert arrows from the top of the quiver when possible. I'd ruffle them up putting back in from bottom. If you have enough arrows in there for the fletching of each arrow to support the other I've never had flattened feathers. I'd see if you had only 1 or 2 in it maybe, or if you tried to shove a dozen in there.
I carried mine with a frame pack during packing into several hunts, strapped on the frame, no issue, but I don't hunt with a frame.
Overall, for me, the Duiker is a very nice set up and I've used it quite alot. Will again in the future.
