Bill, I use Swaro 8x30 CL for my trips out west. I find they are great for peering through the timber and scanning tree lines ahead. Next season I’m adding some Meopta 15s and a tripod in order to walk less (and spook fewer elk in theory). This year was so dry I felt I was likely just running the elk off when moving through the timber. As for 10s, I feel they are neither ideal for spot and stalk for elk/deer in the CO Rockies (bulkier, heavier, smaller FOV, shakier when holding) nor ideal for longer range glassing. For different, more open, environments, perhaps the 10s would work better for me. If I were to make a change, I would consider going from 8x30 to 8x42 for potential low light improvements. I’d want to try them to see if performance met the theory though. Only a few minutes a day it might matter, but it is something to consider.
