I too have gone through several iterations of sleeping pads. We used to use something called Insolite and two of them in winter. Blue foam pads are the equivalent nowadays. I advanced to a closed cell foam ridge rest (48") for quite some time, but a few years ago I purchased a ThermoRest Scout (48") and I admit I sleep very well on it. Not as thick or as light as your NeoRest, but when people ask me how my pad worked the next morning I tell them "I don't know, I was sleeping all night."
In snow I don't feel I need as much padding because the snow conforms to my body shape so I use a 72" Ridge rest and it insulates well enough and weighs only 14 ounces. I wonder how that compares with the insulation provided by the Neorest.
