I am looking to buy a sled. I have rented them for years but I want to buy one that is fit to me. I am 6'5" 270lb. All the people I have talked to have either suggested arctic cat or ski doo. I want to be able to ride standing up without being to bent over. and sitting down without eating my knees. I would like to here all suggestions concerning this matter so I can get the right sled.
