Always wanted to ski a pair of Haute Routs but never got the chance, great find. I did own a pair of 710's and was not impressed got rid of them quick maybe it was just me that did not like them because they sold a lot of them.
I moved to Jackson in 1987 and everyone at the shop skied on Haute Routes - it held the spot in their quivers as THE powder ski. As they were not being produced, us newbies could only hope to have a pair which ironically happend the next year when we bought all NOS that Rossi found in their warehouse. I bought 2 pairs and still have an unmounted pair of 205's. They were fun skis but the GS skis just seemed to do the job better for the way Jackson was skied.
I was always a GS skier so I never actually bought 710s, but my 810s were awesome!
