forpest is correct on his assessment. My Alaskans and Ojibways (2 piece upturned)
work great in all kinds of terrain. However I don't use them due to the value they possess. I wouldn't go wider than 10 inches. The new aluminums are very good. I put them to the riggers on a 10 day griz hunt in the Talkeetnas a few years ago.
We even "snowshoed" across a shallow 30 foot wide stream.
