Mike,
I have heard several guys say "try to duplicate what the carp are eating" but, I have no idea what they are eating...
I have been chumming a place down on the creek for the past 3 days and right now, I can see over 100 carp from 4 to 5 pounds, up to a couple that will weigh over 20 pounds. I have fished wooly buggers, various flies, streamers, etc. but, these carp won't give them a second look...
I fish trout streams and hatcheries in Missouri and the last week in April of this year, my wife and I caught 72 rainbow trout, not to mention losing at least that many, if not more...
These particular carp will occasionally bite a small piece of bread and tied a few deer flies that looked like that, but still no takers...
I'm not giving up though. Sooner or later my time will come, when I can catch a carp on a fly and when I do, my wife says I will be totally worthless because that is all I will want to do. Oh well....
God Bless
