Ralph,

Nice video; thanks for posting it. Tricos on the Missouri are a bit smaller; I gave up on standard hooks for that hatch and tie parachute duns and spinners on a #20-22 emerger hook (Dai Riki 125) to get more gap clearance. My eyes (and casting) are worse than yours, too; I started putting a hot pink Mcflyfoam indicator on my spinners.

Regards,
Scott
