Here's one of the flies from the Carp fly Clinic @ K&K last Saturday. I just added the instructions to the website. The pattern is simple and easy to tie, which kind of makes it nice especially when you're losing flies like I do when I'm carp fishing. It's basically a dumbed down Headstand but catches fish the same and you can tie it in half the time. I like it in Brown, Black, and Olive. You can check out the step by step on the link below.

Also under an indicator it destroys the bluegill, just ask Rylee.
