I agree with you re: the thermal efficiency of the ridgerest etc., its a classic and still a good pad.
I've had a number of inflatables, and I still use a BA insul. air core for general use and more casual overnight mountaineering trips. The lightest decent inflatable I'm aware of is the Neo Air, which I've used, but it still comes in a good bit heavier than a chopped down foamy and can be punctured/torn. One of the main reasons I ended up with the BA pad is the relatively high denier fabric that it offers (particularly compared to the Neo Air) for an inflatable.
The fact that you don't have to be concerned about a closed cell pad failure is one of the biggest reason I choose them for alpine climbing. The others being weight and the ability to hack them up into all kinds of foldable shapes (in conjunction w/ duct tape). A 3/4 GG thinlite, trimmed into a slim mummy shape would be LIGHT.
