ETA: I'll include a few of the pictures of the way the FJN straps attach to a Snake Charmer from
my post in response to @weirdguy's bag hack of the Fournder's Briefcase wedge. You can see more pictures by following the link to the post, but here's what this looks like for the Snake Charmer, with one close-up shot of the Gatekeeper clip attached to the webbing loop. I'm not carrying around any extra FJN straps to easily snap a picture with the Double Carabiner Clip looped into the Gatekeeper clip end (especially since I have a 1" Breve strap that means I don't need to use this hack), but it's easy enough to do.
1" wide FJN accessory strap connected to a Navy (Cordura) Field Journal Notebook (left) and a Wasabi (500d Cordura) Snake Charmer (right). You can see that these straps do not have a Shoulder Pad, are adjustable, and are considerably wider than the 5/8" strap that comes with the Side Effect, but not as wide as the Standard Strap (with Shoulder Pad). They're also adjustable in length, and do not easily tangle.
Closeup showing the detail of how the Gatekeeper Clip at the end of the 1" wide FJN strap connects to the webbing loops of the FJN and Snake Charmer.
