Pretty cool article, and nice to see a divergence from the 'carp are trash fish' and even the 'carp are a great fight, if nothing else' mentalities.
I've never eaten carp, but back when I was a Boy Scout, we fried up a few large shiners (12-16") on one campout and they were just fine with a dash of old bay. From there, I learned never to rule out a fish as a good eater just by looking at it.
