Often, simple, underdressed patterns are better producers. I tend toward the ‘if one wrap is good, two is better’ style. Give the materials, you apply to the shank, room to move, pulse, wiggle. Overdressing causes much of the materials to collapse or compress and be of little value other than thickness. Usually, this is too much thickness if you look at real life insects. 

Overdressed Shroud on Beaded Caddis Pupa

The above pattern has an Antron shroud similar to LaFontaine’s Caddis pupa patterns. It is a little heavy and the underbody of amber brown beads will be lost. The below pattern is a slightly better result with an Antron/CDC shroud.

Slightly less shrouded pupa

Below is an even sparser shroud; perhaps too sparse. However, this gives you an idea of how one pattern can have several looks with the application of materials that either reveal or hide important parts of a pattern’s body.
