like mr barber says,rod positioning is not high on the list of priorities when fishing in weed.the main things are,a rig and bait thats gonna work in the weed,tackle that is up to the job of landing a fish in the weed,a solid buzzer set up is a must if you are fishing locked up tight to a weedbed although i would try to lure the carp away from the weed a bit so you dont have to pull there heads off if you get a take(ever seen the ruined mouths of the horseshoe carp?),also what kind of weed is in the lake?..blanket,canadian,fennel grass,mares tail,starwort etc
