On a recent aoudad hunt in New Mexico with heavy glassing, I used Swarovski 10x42mm EL Range binos with a harness during the stalk, but for the long hours of glassing I used my 15x56mm with the Swarovski lightweight (but solid) tripod topped with the Swaro UTA - Universal Binocular Adapter, which also fits the 10x42mm binos (for closer range). I then could quickly swap out my Swaro spotting scope (which stayed in my pack) when we found animals to check them out. Light is good, but light and solid is better for long hours.
