In reply to galpinos:
No, I borrowed the Ultralight for the trip, haven't tried the Comfort Light. My NeoAir is the women's x-lite, and I do find that comfy, but found the Sea to Summit one more so - whilst the NeoAir has horizontal baffles which provide good lumbar support, the S2S one is in construction more like a pocketed sprung mattress, so I find it more responsive and supportive.
Cotswold are selling the Comfort Light Insulated, so you could pop in there and try one.
