Replying to Glidecam vs Ronin M

Getting ready for winter and getting the fear all ready and the budget allows for some new toys. Iv got the old trusty Glidecam that is my workhorse but a friend of mine just got the Ronin M and has had nothing but good things to say about it. Has anyone here taken one of these on snow? I'm concerned about the battery and the cold. But I know I would use the Ronin M a lot more outside of winter shots. Input? Suggestions? Thanks!
