Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I may be nieve but when it comes to trailing shucks I use what ever color poly or antron that's handy.
The Trout don't seem to care.

I have noticed a good amount of baetis nymph shucks tied with an orange antron or similar material. What do you folks think about the right color for a shuck?
