Thanks to everyone for the help with my original post. My next issue that i have is which one should i get. I am at a crossroads with which temp rating i should get the 40 or 20 degree. I will mainly be using it for 2 seasons spring and fall. I will not use anything in the summer months. Is 20 degrees to hot for spring. I don't want to be sweating if it is 45-50 degrees at night. I am also up in the air between Outdoor Equipment Full Length Zepplin UQ and Hammock Gears Incubator. Thanks for help.
