I have a superfly for my wbxlc. My son uses an edge for his wbbb. My wife has the largest of the DD tarps for her dd and my daughters skeeter beater in bunk mode. But we have two more hammocks for any kids who come over and wish to try the hammock thing. Those we do not have tarps for. If they are very young kids we double them up with me and my son. If they are older however we use a blue walmart tarp in a corner to corner set up. Two corners tied to the trees and two to stakes. The coverage is ok. Not tried it in a huge storm but so far no one has gotten wet. You just have to be sure that the points are longer than the hammock that are attached to the trees. Otherwise you will get water running in on you at the ends.
