I use the Jet Sled. Works great , I have the 54 x24. I've spoke to a bow tech who liked my sled and said he tried the Dead sled(If that's the one that rolls up). He said it was horrible, flipped over, took a long time to unroll and attatch the deer etc. It may be nice to have one to pack in not knowing if you'll need it but if you know you have a body to drag out your bettwer off with the Jet Sled. Also you can haul supplies in or use it as a tobogan if need be. Thick enough to last many trips over rocks. Also you can buy some kind of slats to protect the bottom.
