I've had great satisfaction from the Bushnell 3200 series. In Alaska I would think anything like their Rainguard coatings would be preferrable. I have also had great experience with some of the Medium priced Burris, from the Fullfield II and up, even their Timberline. The old Nikon Monarch and such...but Leupold is my maintstay nowadays. If your rifle doesn't have backup irons then just take an extra scope in mounts that you can fall back on for a spare. Go hunt and have a ball!
