thats a link of hangnout camping with his bridge with the leighloquilt. his daughter makes them so it might have been special but I dont think so. but you can always PM him and ask
I think you- or someone- will just have to try it out to know for sure.
As far as I know, JRB does not make a quilt especially for a bridge. I don't think they changed their original quilt designs (may well be wrong) when they made the JRB bridge. And they say all of their quilts can be used on their bridge, as well as non-bridge hammocks. Maybe the bridge itself was designed to work perfectly wit their quilts?
I can say their bridge and the MW4 work as though a custom fit. It appears to be a simple rectangular cut quilt though with a dif cut.
I have a MMP IX UQ that was designed to be used on a HH Explorer. Amazingly, it seems to work perfectly on the GrizzBridge. I have not tried it on the JRB bridge.
I have tried my synthetic WB torso ( seems identical to a "Yeti") on the JRB bridge. I used to think it did not work because there seemed to always be a gap between my spine and the quilt, though sealed well around the edges and ends. But I tried it again recently with more tension and it seemed to work better. Jury is still out.
So, not much help from me except to say you will just have to try a quilt to see if it works. Or, custom made for your hammock. Maybe some one else will know from personal experience.
