I had a wide one for 5 years, put the runners on it right away, Pulled it maybe 3 times behind a wheeler, rest was by hand. I can say it definitely helped on asphalt or concrete. On snow I couldnt tell the difference. I think every sled is going to get heavy when pulley by hand regardless. Even with a smitty sled it can be a bear. Last winter I went to an otter cottage, Never put runners on it and pulled it behind the atv all year, on concrete at the landings and in my driveway it sucked. Alot more weight to the cottage than the Wide one though.
