You’re exactly right. Not sure how strong the buckles would be vs the dedicated grab it lower straps but in theory it would work just the same.
I cut the shoulder straps out of my guide lid and just use the straps with the k-clips from the bottom of my bag when I want to run it like a pack.
Mrbill, what weight were you able to get the guide lid down to.
Last year I modified an Argali to use on a SG xcurve frame. I am working through some more mods on it right now and lan to try it on their Evo frame soon. Currently it sits at 1lb 8 oz. (On an OMP bow scale) I have some more trimming to do but on the Evo, that will be lighter than SGs 40/56 bag - under 4 lbs.
I have no issues hacking my guide lid! I'm just curious what i could achieve.
Thanks.
