6'0" 205 lb side sleeper. I was in the same boat looking for a wide but not long pad. It's annoying that most wide pads are also long. I was using the neoair trekker wide torso. Worked ok but wanted something a little longer but not 6.5 ft. I ended up getting a klymit static v. I used it last night in the back yard. It was super comfy but I don't think it would be real warm. For me that's a non issue as I'm only able to go out in the summer for the forsee able future. If weight is an issue then consider that the long wide neoair xlite gives much more pad and insulation for the same weight. It, the static v and trekker all come in at about 16 oz. I like the static v because it is easy to blow up and low price. Also had less problem rolling off. I didn't have to under inflate to stay on.
Pillow is a problem for side sleepers. I am using an inflatable despite the sleeping on a balloon feeling. I made a stretchy fleece pillow case which helps. The pillow is actually a disposable hospital pillow. Less than 1 dollar from medical supply companies.
