Going to vary with how you hunt. I do alot of hiking, but also lot off road glassing. I have small packers and large rig scope my All round favorite is Leo 12-40x60. Scope is not much over 12'' is 32 oz. can pack, real nice for spotting qiuck on 12x.I made a mount that sisters with my terrapin.I use it by far the most. Wish I could get a hd model with tmr ret. For real open country n rig glass, like antelope areas.My Kowa 20-60x82 is great, I like the 30 wide eye pcs. on for most glassing
