If they work. I like the bigger foot print but I think its going the wrong way. I think they need to be long not wider. Also they dont start working in slush till you are already sinking so I could see them just digging you in a hole still. I saw the video on youtube. was not impressed with the stuff they were going through. I want to see them on oneida with 6" to 12" of slush and snow before I would spend that kinda money. I could be wrong just my observation on what I have seen and the thoughts that roll through my head.
