installed the rev skidplates under the a-arms,with a little redrilling and cutting of a corner as not to interfere with the schockaction they fit perfect,actually better than on the rev where you have to use all the provided clamps.i only used one hook on each a-arm.it's on there solid.as how my new hybred yammi-doo ski's worked,as discussed in the powder pro ski section,they work absolutely awesome.the ski's provide a lot more agility and tremendous fotation.so with these alterations MOUNTAINCLIMBERS look out.next thing i will be looking at is if i can lenghten the frontschocks as to get a little more angle on the a-arms so the sled sits up another couple of inches,revelstoke here we come.by the way it snowed over a foot in town today.and earlier the big sleds couldn't make it up on boulder with that much powder.they groomed on the weekend.have a good night.paparattler
