I have the AGC with the Max pocket and the FHF harness. I enjoy both of them, and see how they have different purposes they can serve. The AGC would be nice to store additional items in. FHF is more of a compact, run and gun harness. I can attest to the neck rubbing from the FHF, however, if you get the strap covers, it alleviates the problem totally. I have noticed, with bulkier clothes (I run a bino harness whitetail treestand hunting) the FHF straps are not long enough.
I'm really liking the Outdoor Vision bino harness. I've owned them all, and I mean them all haha. I settled on the OV harness. It seems to meet all my needs perfectly.
