Twist on a Crayfish Fly Pattern

I was watching a Barry Reynolds video on YouTube about fly-fishing for carp.

One of the patterns he likes is Dave Whitlock's NearNuff Crayfish.

That's a great-looking pattern.  In searching for the tying instructions for that, I stumbled across Davy McPhail's carp-crayfish pattern video:

I liked Davy McPhail's pattern in that it didn't bother with claws.  Studies have shown fish will attack a crayfish without claws before striking one with claws.  I made this pattern even easier by omitting the eyes.

I think this is a good-looking pattern as well, is VERY easy to tie, and stands up nicely.  I tied these on size 8 and 6 hooks.  I can't wait to try it on some fish once the ice melts off the local waters!

Another crayfish pattern, the Foxee Red Clouser, also looks really good.  I've tied some, but haven't put them in front of fish yet.
