I might be doing a solo trip this year and contemplating a couple gear changes. One is a compact spotting scope. Looking at the Vortex Razor 50mm HD as a possibility. It goes up tp 33x. My current scope is a 20x60 60mm. The compact would be about 1/2 the weight and much smaller. The other change is a more specilized pack like the Stone Glacier. It would cut 4 lbs off the Barneys I currently use. Comments on these changes? Am I giving up too much with the smaller scope. The Barneys is bomb proof but heavy. Do I just stick with?
