Just came back from the Pine lake 200 where my nephew won his class on a AC fan sno pro. Boy can those F5 turn well on ice I think AC took all the classes. This was a susprise to me comming from Polaris and think how well the gen 2 can trun but they were no challange for the F5. My hat goes off to AC they have made a fine chassie. The race does not have a 440 class it has a 500 you can race a 440 if you want to most of the bigger name pros chose to run the XC 500 some were the Gen 2 othere were in the edge chassie. Winter won the 20 lap 5.5 mile finale by a comanding lead. Great fun and we won our class and took 2nd in the 500 with a 440 fan.
