There is good discussion of bumper plates in my build thread from the last few days. NV, Swag, PS, ... plates fully wrap around the crossmember. GR and Barnes do not. The wrap adds needed strength and protection to the crossmember.
I upgraded my hammock, I'm a big person so I bought a double size underquilt, it's matching top quilt and a new rainfly.I doubt I'll use the stuff until fall, but I wanted to buy it early so I have some time to work out the kinks before I head to the Hoosier National Forest.
