Due to the fact that the SKED stores in a roll, it naturally wants to maintain that position until fully deployed. I find that it bothers the patient, in that the ends roll inward. I've never used an Oregon Splint, and I've never used a KED for wilderness application. It's easier to strap a SKED to the board, and put it in the stokes with the rest of the crap we haul out. The way we play it, if you're in the wilderness, or in a park, on a trail.. and you need to be carried out, you're getting fully immobilized for convenience of us, regardless of injuries. It's easier to manage a patient that cannot move, at all. Therefore, we put them on a spine board that's rated for the types of rescues we do. Never, never, never, will I use, recommend, or even accept.. a Miller board. Junk. But I feel if they need carried out, they'll be getting strapped down so they can't move around, tumble off a waterfall, broken ankle or heart attack, strap em' all down.
