I like to go more with Nike swoosh shape than the standard U we put the blinds in the decoys 5-8 feet apart with 4 or less guys tighter if more but I don't like hunting more than 4 guys to a spread. We will be in the middle of the fat part of the swoosh with a long tail quartering down wind on one side and a short tail quartering the other way down wind. We usually know which way the birds are coming from so we set up so that the birds will hook just beyond the short tail of the swoosh and the long tail will push them into us. We also put 3-6 goose magnets on the outter edge of the pocket made by the swoosh 15-20 yards down wind of the blinds. I like them closer but some of my hunting buddies are short on self control and will shoot them if they're closer. This is my standard set if I can't scout, if I can I just try to do what the birds are doing. I also like 5 or 6 to one sentries to feeders especially in tall stubble
