Coley,

I'm reminded of Ed Ward's remark that everything about the Intruder is "engineered" (in his words) on that pattern. Each and every material and the way it is tied in serves a specific purpose. So the salient question is whether each material you used is tied on in a way that provides action and creates the illusion of being large without being bulky.

Bucktail generally doesn't have much action in the water compared to marabou, ostrich, emu, rabbit, and artic fox, for example. Rabbit is great for action, but comes with the cost of quite a bit of bulk and a lot of resistance to sinking.

The colors of the Green Butt Skunk are a proven combination, so that fly will catch fish - as will most any fly. Does it sink like and have Intruder action?
