Wing Cases: Thin Skin or Turkey Feathers?????

[Eight Thumbs]

Hey Folks,

I've just whipped up a couple dozen GRHEs to fill in some of the empty spots in various fly boxes and to help fill the single, mega box I'm going to carry instead of a vest on the trout stream from now on. I've tied some with wing cases made of feather slips and others with wing cases made from Thin Skin. I like the Thin Skin better for ease of tying, durability, and general appearance. Which do you favor for flies that require wing cases? 8T
