Fellow bridge hammockers, I am looking to get information on deep winter camping.

I have plenty of experience doing deep winter camping out of a GE hammock at this point.

I just recently found out how much I love bridge hammocks. I am thinking of getting some new underquilts for the bridge hammock so i can use it in the winter instead of my normal setup. Has anyone done deep winter hammock trips in the bridge hammock? What did you use for insulation? I like how in a GE you kinda get the underquilt to help insulate your sides but in a bridge hammock you really dont have that much double coverage. I have also taken a sleeping bag and cacooned it over my entire setup when in the negatives and i dont think you can really do that with a bridge hammock...

So how about it? anyone got some good information either on youtube or just your personal experience you can share?
