Im going on a west bound trip to the big horns and was wondering if my F6 SP will do alright. im from minnesota so i dont own a mountain sled. just a ditch hopper. a friend says it will do fine but im not so sure. 2 years back i went and rented a M7. that thing was awesome!!! where we are staying rents polaris and yamaha. if i do rent which should i go with?
