I am also looking at the WOOX Superleggera Stock for my 6.5PRC build. Pretty light with the polymer infused carbon fiber. If I go with the WOOX, I will go with the adjustable cheek riser.
Bumping this thread up. I'm also interested in Woox. I love the wood look but it has some modern bells and whistles to it. The Tupperware stock on my 110 ultralight definitely needs to go but as much as I want to "want" a chassis or full carbon fiber stock I just don't know if I personally like the look of them for my hunting setup. If I can find enough positive reviews/experiences on a Woox Superleggara i'd rather invest my coin in that since it tickles my fancy more, but if it's just a piece of hot garbage, I'll begrudgingly invest in a carbon fiber stock I guess.
