A backup scope is prudent for such a hunt. My own thinking would be to pair the Zeiss with a proven fixed 4x scope (Zeiss or Leupold), with both main and backup in quick release rings.
1) absolute confidence in reliability of backup
2) 4x is perfectly adequate magnification for the critters being pursued
3) light enough to stow easily in pack
4) not financially burdensome

I think that's a great idea but I'd probably pair it with a 6X instead of 4X, but it's all about the same.
