I'm sure it would work, I use snowshoe hair intentionally on this pattern though, I think it maintains floatability better...I use cdc on a lot of my other patterns but this one really catches a lot of fish and I think it resists being slimed much better. There are times when I really don't like the maintenance Cdc needs. Black flies hatch in cloudy rainy weather a lot
and snowshoe holds up to rain better. It is also really translucent and that may play a part in its effectiveness. Snow shoe and Cdc each have their own attributes and there are some patterns that work better for me with one or the other Part of the reason I like tying flies is really refining a pattern until it does what I want it to do. You ought to try to get some snowshoe hare; I like em both!
