Any one try these out? I am looking for some running board inserts for my sled so I don't have to kick my sled every 2 minutes or worry about falling off due to the ice build up. Airframes would be idel but they are out of the price range this year. I was planning on getting the xxxmodrods monster boards but came accross these RSI boards. They look like they would be pretty good just looking for some opinions or if anyone is runnign these RSI boards or has and how they work and if they add to or keep the rigidness of the stock boards. Thanks!
