Replying to Go Pros for filming

Hey guys,

I am currently filming with a d5100, 8mm rokinon fisheye, cam caddie, and a takstar shotgun mic. I originally got this setup for filming skateboarding and it has served me pretty well. However now that I am getting more into filming skiing I need some advice. Though I don't have the most expensive setup, I baby my camera. Because of this when its snowing I cant film. Also because of its large size I cant really bring it onto the mountain for casual filming. This means that I have to go into the lodge and deliberately film for a while and I can't do anything on the way to the lift because I am carrying a camera. This is very annoying as I would like to film some casual clips with a decent quality (not phone), and little to no setup per shot. So my question is: will a gopro satisfy my needs.

tl;dr will a go pro be good for casual filming, but stilol give decent results.

Thanks Guys.
