So I am in the market for a new flip over (full thermal) and have it narrowed down to these two. I looked at them last year as well and thought that the otter had an advantage as they seem well build and have a good rep for a very rugged sled. Looked at them the other day at scheels and the otter sled seems lighter and more flimsy than the Clam sled. Did otter change there sleds? Really like the bright grey interior of the Clam sleds. Should make finding stuff easier. I mostly fish DL, LOW and Winnipeg and gets pulled a fair amount behind a snowmobile.
