That right there tells me both are good to have. My hunting style right now is having a base camp using my truck to get to an area then hiking at most 2 miles in somewhere and hunting. To me the 77 can do this. Where that 55 would be huge for backpack hunting or even the guy or gal who only uses a spotter to verify and never uses it to scan with. Those types ahould absolutely go with the 55, price, image and weight alone. Thanks for sharing that, nice setup!
