Anyone have experience with the yellow Ames Snowboss shovel shown here?

What I like about it is that the left hand has a handle to grip so the
hand doesn't slide up a slippery pole away from the blade toward the top
handle. But I'm not wild about its being made of plastic. And its 24"
width can make the snow load heavy, especially on a warm day when the
snow has melted and is heavy.

What's been your experience with shovels with offset poles (like the
blue Ames Superlight 18" shovel to the right of the yellow one)? The
claim is that they are easier on the back.

Thanks,
