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? Just trying to gauge my odds of staying as warm as I do in my GE.
