The Fall River is snowy, and that makes access a little tough compared to the Met and the Crooked, but worth the effort because the fishing is also good on the Fall from the hatchery area up to the Camp Ground and the Headwaters.
Eggs, micro streamers, perdigons, Zebra Midges and some minor hatches of BWO #18-20, Midges #22-26 and small black winter stones #16-18 you’ll need 6.5x or 7x to fish effectively.
I’d rate the Fall a 7 or 8.
