So as an update I used the FHF rig for a deer hunt a couple weeks ago and I’m pretty satisfied. I was using 15’s as my primary binos and did not carry 10’s most of the time. Here are my takeaway pros and cons (+/-)
+ holds my 15’s
- 15’s have to be sideways
+ also holds extras like RF, (clipped to the front or works w/ FHF RF case), lighter, knife(s), tag, chapstick, mirror, whistle, SOL bivy, snack or two with space too spare - basically everything but a water bottle
- kinda big, and lumpy if you don’t pack carefully
+ I think will work great for fly fishing and photography
- cordura is not especially waterproof and can soak up water (potentially stinky and extra weight)
+ seals off contents from dust (good enough for me anyways)
- probably not waterproof and zipper isn’t as quiet as the typical flap+tab setup in most harnesses
+ I can use it as a backpack lid when I use 10’s in my regular FHF or RYO harness and detach it from my pack for stalks
- every little accessory is sold separately so it adds up $$
