Came across this thread on a different forum and thought you (Misha) might find it pertinent. If you scroll down they compare Trango Extreme/Prime, Batura, Nepal, and Spantik.

PS Note that the Scarpa Omegas bdynkin recommended now come with Intuition liners out of the box, and weigh less than the Spantik or Nepal and about the same as the Batura. I was practicing with my Omegas in the rock gym earlier today and had forgotten how light and relatively comfortable they are for plastic.
