I agree with Compo Rocks...these are excellent skis. I have recently bought a pair of 2009 MY with Fischer Z11 RF2 bindings in 170cm. I was looking at RX8s in 170 cm but when a deal came up on ebay.de I had to purchase these skis purely on the comments on this forum and other sites with no demo.
Last week I skied 242kms in 6 days in the Italian Dolomites and these skis never ceased to amaze me and build my confidence. I skied mostly on fast red and some blacks and blues and this ski is fast and stable in the carve and in any radius. The edges are great and when you push into the ski during the turn you can feel them pushing back with some energy. As they weigh only 9kg with bindings, you don't feel tired skiing them all day. I'm in my 30's and still fairly fit, 82kg / 180lbs and 182 / 6' 1. I did find they maxed out at arouund 90KPH / 55 MPH see...that me skiing.

I fastest I saw that day was 102KPH but on a normal slope their wasn't a single person who went past me all week. I also have a three year old son who started skiing this year (Fischer RC4 skis :o) ) and I could use these same skis for slow speed training. I can't recommend these skis enough for anyone who wants to stay on piste!
