I have the AGC and use the bottom part for my GPS, while my RF is attached to the left strap harness.
I like it as it organizes a lot of stuff I always want on me.
My Swaro 10x42 were tight, until I removed the lens caps from the Obj lens.
I have since ordered the Badlands version (XR I believe ??) that has the same type of set up
- bino pouch, GPS or RF pouch below that, plus 2 side pockets, and a back pocket as well as a rain cover which is removable if desired.
I normally have my wind checker in my AGC top stretchy area, quick easy and do it without looking.
Not sure I will like the change with the badlands to have it in a zipper side enclose.
You know how hard it is to change when you get used to something
lol
Anyway, I believe if you can get used to the bulk up front, you will love it.
If you are one of those guys who just cant tolerate all that mass on your chest- none of them will work for you.
With that said- get the AGC set up with 2 side pockets, a bino pouch big enough for 10x42's and a lower compartment for either RF or GPS.
OR
Get the Badlands (new one), that does the same thing, while a better bigger RF or GPS compartment.
The badlands is a bit heavier, but seems to be better for me as with my AGC I added a pouch for the RF anyway. And on the badlands I can tether the GPS to the side with their hidden set ups- pretty cool.
