I think not only weight itself but the balance, focuser position, shape/grip, hand size also play significant roles to the shake of the binoculars. I have small hands and can keep all the small pocket binoculars steady. In that regard Curios are very easy to use. All of my mid sized binoculars including UV 10x32 HD, NL 10x32 and Monarch 7 8x30 are very stable in my hands. However, NL 8x42, SFL 10x40, Habicht 7x42 and 10x40, all the full sized binoculars are not very stable in the use. Funny thing is DDOptics nighteagle 8x56 which are the heaviest are very stable in my hands.
