When I take delivery of my new machine I'm thinking of swapping skis right away from the stock 6.9 pilots to Powder Pros. I've had these skis on my '01 MXZX 700 136" (unstudded 1.5" ripsaw)for a couple of seasons with shaper bars and love them, great cross over skis. I know ZX chassis to XP chassis is like apples to oranges. Opinions on if this would be a worthwhile up grade or should I stick with the Pilots? What are the 6.9's worth if take 'em off?
