Hard to tell the actual size of those buds, but Id say your going to keep more then a 1/2oz. Some of those buds are fluffy but some of them look pretty dense. As far as the harvesting...getting a 30x magnifier is really, not that hard. I mean unless you live in buttfuck nowhere...I dont see how its not worth the tiny bit of cash and effort to maximize the crop you spent so much time on.
