sparman - For what's it worth. I'm located in the Denver, CO area and fly at 5200 - 5400 feet altitude.Have one of those planes with an OS 46ax and its a lords plenty unless you want to get real redical. Last two flights, when it got above freezing, were with skis and handled that nicely. Unfortunately ran out of fuel and had to hike a long ways thru knee deep snow to retrieve.

As one of the other gents said - its a bear to get off the ground.
