Before light....... go with the glo chartreuse (yellow version) head and rainbow feathers... I rarely fish that hour before daylight anymore... but that jig has worked for me many times in that window.
Sandy - 1/4 oz Maxi Jig, pink head, pink and white body, two red beads on the hook shaft (have to have the beads). That's been my go-to jig for many years on the Sandy and usually will get me a fish or two on most of my trips.
Clack - Our go to the last couple years has been a 1/8 oz nightmare (various manufacturers), black head, black body, red accent collar.
All white nightmare has also done well on either river.....
