i have yet to catch one on the surface, but a lot of the carp out here feed on midges when they are hatching. i've also seen them chow down on cottonwood seeds...quite the sight!
one thing i've found is that the carp where i fish are leader shy. if i fish 2x or 3x i don't get as many takes as i do with 4x. of course 4x and a 20lb fish make for a dicey combo!
