Every time I go up to 11 Mile Spinney I stop by the local fly shop bring a dozen donuts for the guides who are heading up there too for the day and ask what they’re using right now, otherwise you can flail around up there all day changing flies and not catch a thing. BTW biggest Spinney trout I’ve caught was 7 pound brown October about 9 PM on a mouse fly.
I’ve fished a bunch above Spinney it’s a bit tough to get to watch out for the Buffalo but has huge fish in the fall well worth it. I live about 60 miles away.
