I've had them on my 08 RTX for the last 2 seasons and will be running them this season aswell. Not too hard on the arms, plenty of bite in the corners and the small half round keels on either side of the main keel help reduce the darting....great ski over all and well suited to the Nytro. I ran a 7.5" Shaper bar on them, no complaints with the ski at all. Best of all they are priced right!
