I like fishing CJs in 14 & 16, standard color, in small streams. They get down fast, have a lot of flash, incorporate peacock herl (which is like trout crack), and are nearly indestructible. Perfect for a stream full of hungry brookies in a setting that will doubtlessly include tight brush where a bit of lead on the line is undesirable.

For my flies, I dont epoxy the back. I will, occasionally, however, coat the thorax with a thin layer of CA glue, which I wrap my herl on top of. I think it keeps that portion together longer, which is usually the first part to come undone on any fly with herl.
