Exactly my set up for quiver & carry...you will be very happy.
Best thing about the haversack? You will love that it is silent. Ever try to go into your gear bag for something like a grunt call.....on one of those silent crispy cold mornings? The GFA Haversack is absolutely silent.
With regards to the GFA Quiver....spend some time experimenting with strap length. I leave mine fairly long, and am forever moving it's position on my body based on what I'm doing...walking through a field, open woods, brushy area, climbing, etc. Very versatile.
