Sleds only work in the goose fields for me. Most of the terrain is too rocky for a plastic sled. I have improvised one out of corrugated tin roofing and it helped. On the roll up type I would be temped to get some MDP and mount the front grommets in that, I would reinforce the side ones with 30 mil PVC pond liner. If the grommets start to rip out the sled would be worse than useless.
But I would be more likely to use a frame pack and make two trips.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
