Tie them sparse with little to no flash
Michael,
I hear this every time I am around someone talking about carp, and I tie my flies according to this rule. Now, let me add that I do not catch carp in the same capacity that you do, numbers or weight. But this weekend I pulled in a decent-sized Buffalo. Granted, it is not a carp, but cousins, maybe? I used the flashiest fly I had in my box: clouser foxy minnow.

What are your thoughts on the flash vs. no flash theory? Are Buffalo and Carp that different?
