I prefer one with a D handle and telescoping shaft. The D handle seems to work well with mitts on and the longer shaft makes it easier on my back.

I currently use the following model when backcountry skiing and winter camping.

It does not have the long neck protruding from the shovel blade which makes it more packable but still has a very solid connection between the shaft and blade.
