Last year I used a Gossamer Gear Nightlite torso (foam pad) over one of their full length 3/16" rolls of foam. That worked okay. I think the pair weighed about 7 ounces.
This year I think I'm going to combine a Neoair small (47" long and 9 ounces) with the GG Nightlite (or maybe a cut-down Ridgerest or Zlite). The Neoair goes from my head down to lower thighs, the foam will be under my feet and calves. I like the idea of having foam that's big enough for my torso if the inflatable part fails, plus I like to have the foam anyway to use in my backpack's foam pocket to add structure. I think the Neoair/foam combo will weigh around 12 ounces.
The Neoair I got recently is old "rectangular" version that's an ounce heavier than newer version. Campmor still has some available at decent sale price of $80:

Don't most inflatable pad manufacturers have lifetime warranty, so you can send back and have repaired if you can't fix a leak? Not ideal, maybe, but better than scrapping your current pad.
[EDIT: I just checked a couple manufacturers and they have "limited lifetime warranty". This would not cover fixing things like a leak from a puncture, but seems like it would cover repair of a leak from a failed seam.]
