Check w/Shawn Carlock. The one he uses would be right up your alley. It's on his first video and there are post that identify it if one can master the search feature.

The best way of carrying, at least for me, is butt down in a pack. In snow a plastic sled is tops, if runners are installed and provisions are made for it to not slide back wards.
