I looked at the Kolibri toady and it looks like itd have to be pretty intense to have a rope bridge. The only thing I could come up with was taking the webbing apart, taking the D's the the bridge runs through out, and then putting it all back together with some rings, and splice a bridge on there. Or tie it, depending on your resources. Kicker is you would have to un-stitch all that webbing to be able to remove it. which would then have to be stitched BACK (unless you did some serious modification). Possible? I think so. I mean the re-sewing of the webbing could mean the difference of your leg loops falling apart.. no big deal... Im not gonna lie I personally would try it if I had one to mess with, Definitley a risk though...
The snaps are nice!
