Salmo- In steelhead green water, the last two trips we've hooked 40 fish on 12mm beads. They work in not just gin clear water quite well.
I made that birght orange color one just for higher water and it has been my go to so far this winter.
When I was guiding the Methow last fall we ran 12mm or 10mm beads... and they chomped them in the clear water so I dont think it matters too much.
