Both have their place, give me a call and we can determine which is best for you. Your goal is to provide a plentiful and nutritious food source. The more area planted the more of a superior food source you will be able to provide. I like plots to be 2 to 10 acres. If your plots are smaller then you will need more of them.
Small plots tend to be over grazed very quickly.
Try to utilize every area that you can in addition to your plots such as roads and fencelines. Planting rates are guides to go by and need to be adjusted according to the size of the plot and the number of animals using them. The smaller the plot the thicker it should be planted. Say for example the planting rate is 25 lbs. per acre and your plot is only acre. Plant that plot at 25 lbs.
