Seems like I, too, am coming across the light hitters. Especially when fishing flies in smaller sizes. @Dillon 's comment struck me as what's working best now also. Seems when they are out away from you keeping tension on, especially early, is important. I found touching up the hook with a hone often helps the initial hookup numbers.
Unless I'm fishing boobies. I'm not fishing those much these days as they seem to occasionally get swallowed.
