Any consensus yet on NeoAir vs. ProLite Plus?

…

Frankly, I don't know how you guys use a real short or torso length pad and put your pack under your legs.

When I go to bed at night, my pack is empty. How much extra stuff are you guys carrying? I hang my food bag, pitch my tent, and if it's cold, I wear my clothes to bed, my shell or any extra little insulation becomes a pillow. What's left besides a few hard misc items like fuel/first-aid kits, etc?

Would there be much of an r value increase with a large neoair over a regular z-lite? Would I have to use the z-lite on top?

R-Values are supposedly cumulative. 2.5 for the Neoair + 2.2 for the zlite =4.7 R-Value. The debate goes on for whether or not the zlite is better on top than bottom.

The problem with trying to hypothesize over comfort levels is because there are too many variables–most importantly individual preference and tolerance for comfort.

Yeah I heard that but my question was about having a 25" neoair over a 20" z-lite. Would the 5" of overhang over the z-Lite greatly reduce the thermal effencency rather than having both pads 20"?

You could probably come up with a mathematical formula that would say some heat would be lost, but I doubt you'd be able to feel it.

But, putting the zlite on top would negate that issue I think.
