We have a combination of board and horsecote/hotcote wire. The board is about to be painted black and is on the stretch facing the house on the pasture as well as the small turnout/sacrifice pen by the barn. The wire is hotcote top, middle and bottom and horsecote on the two remaining strands. Right now we are saving towards fencing another portion of the property so we can use rotational grazing - the area we have right now is right on the edge of not being quite enough. In retrospect, I wish we had done 4 board rather than 3, we may fix that when we do the next bit.
