These are 2 of the advertised weights i've found, in 11-32.......

pg -950 (did you mean 850? it's 8spd) 280g/261g
pg -970 330g/307g
pg -990 290g/282g

weights seem to be different between a couple of catalogs I have here

I have the 990 PGII, it's pretty light. One thing about cassettes, when you are looking at 990s, XT and XTR, the biggest diff is in the lockring. Most of them have aluminum (or composite in the sram) carriers, with steel rings, but that steel lockring vrs an aluminum makes a pretty big diff. It doesn't shift quite as smooth as when I was running shimano stuff, but it works, no complaints.

You can usually find some pretty reliable weights here; http://weightweenies.starbike.com/listings.php
