My BPing partner loves his MS ghost. And I see that the ULA circuit also has a following.

The MS Ghost has a fiberglass suspension hoop and the ULA's is made of delrin. I want to incorperate a similar frame into my G4 to make it more comfortable at winter weights. This would allow me to add load lifters as well. I would also make it removable and incorperate it into my idea for a sil-nylon chair sling.

So has anyone ever removed one of those things and checked out the material? Is it straight when relaxed or in a U shape? Is it flat or round?

Any idea as to where I can buy something like it?

Thanks for any input.
