Not all 25" pads are the same and different people find different styles more or less comfortable. The Neo-air has horizontal baffles... other pads have vertical baffles.

I am a big guy and I found the REI Stratus large to be pretty nice. It has vertical baffles and the outer baffle on each side is slightly larger. My shoulders span the entire 25" but the slightly larger baffles make it feel like I am solidly on the pad. Other 25" pads I always felt like I was about to fall off. Another manufacturer out there uses oversized baffles on the outside, but I can't remember who at the moment.

Of course a custom kookabay pad would have been perfect for you but alas they are no longer in existence.
