rob,
the guide had us using hook side up flies....clouser type, crayfish, and the like. the one that caught most of the fish were a copper upside down zonker. carp are ultra spooky. a cast 30 feet above them could make them pull of the bank, an achor 'quietly' lowered into the water, 50 feet away, to fish to 'risers', would put them all down.....wwayyy spookier than trout. as much as i am a dry fly person, the carp we fished to were in 6 inches to 4 feet of water...tailing, gulping in the foam, mudding...very cool stuff. i would recommend it to anyone.
btw, after more than 20 years of fishing the mo', this year is in the top 5 for fishing....dries everyday, all day. in 7 days, we shallow water nymphed for about 10 minutes.
good times!
