The Rush was an over hyped joke last season. Minnick and Olstad did not want to ride the Rush because they kept breaking it during testing and actually converted one of their Rush's to a standard tunnel and skid but Polaris told them they could not run it. Greatland Welding completely rebuilt and reinforced the Rush rear skid to make it more durable.
The stupid, front mounted heat exchanger on the Rush's hurt them bad in the low snow conditions of the race. Kinda hard for snow to spray up on an exchanger that is mounted in front of the sled, high up above the trail.
If the fact that not a single Rush finishing the Iron Dog is not enough proof that the sled was over hyped, how about Polaris sponsored racers Bunke and Davidson? Davidson never rode a Rush for in the USCC races and Bunke went back to his IQR after two races and stayed on it for the remainder of the season.
The Rush is nothing more than a modern Xtra 12. It is made for cruising, fat guys and Polaris kool-aid drinkers.
