I realize you already made your decision, but someone else is liable to read this, so...
For what it's worth, I much more prefer the Arrowmaster. I even have one to use for 3-D. The acessory pockets are great, and it's infinately adjustable. It works great alone, with a back pack, or a day pack.
I haven't used the GFA brand, but I made one like it several years ago. Never really liked it--in thick stuff, arrows got pulled loose regularly. the fletch cover I made for it also got yanked off a lot. I'd given up on finding "the" quiver some time ago, and was using a cheap hip quiver (worn GFA style)until Rod designed the Arrowmaster.
I've used my Arrowmaster in the mountains of CO, creek bottoms of MS, at 3-D tournaments all around the Southeast, and am taking it to NM in a week. I've tried to find something wrong with it, and I can't--it works better than any quiver I've every owned, and I've spent a small fortune on quivers over the years.
Nothing against G. Fred, the Arrowmaster is just a better quiver for me. Rod has also done a lot for our sport, and continues to do so.
