The Spring Miller is an effective cross-over patter from warm to cold water. It takes most all species of fish the "look up". From Blue Gills year around, to Trout in the tail-outs in the evening and Smallmouth most everywhere you find them. I twitch-retrieve on still water and let it swing into the tail-out of a pool on rivers and streams then twitch-retrieve for several feet.

Good one, I like patterns that tend to keep the hook eye free from any potential exposure to head cement.

Thanks folks for the kind words.

Yessir. I've done well over the yeas with a rabbit dubbed body and woodchuck wing as well.

I definitely have to try that for the gills.
