It’s worth trying! My favorite carp/fly fishing experience was a day that started out as a bass fishing day. The lake that I was fishing had a shallow (1-2 feet) mud flat where a trout stream entered. On the flat, several pods of carp were feeding on the surface. Since I was bass fishing all I had were my bass flies…however, I did have a few adult dragonfly imitations. A soft cast within about two feet of a fish resulted in a very agressive attack followed by a 10 minute fight. There were even a few that missed the first time, turned around to find the fly, and gave it a second shot. I believe the biggest one was 23″, not big by carp standards, but still a blast!
Some guys on a pontoon boat saw me fighting one from a distance and came over to see what I was up to. They looked confused when they saw that I was actually fishing for carp. Too bad for them.
