What is the cover like on the place, and next door? Is the 100 surrounded by places that hunt? If you're trying to draw from next door, I would lean towards multiple feeders. If you're trying to keep them at home, I like the central feeder idea better.
I agree 100%. IMO, one of the traps many hunters fall into is to view feeders like fish hooks. Just put up more feeders and you'll have more deer, right? My experience has been that "less is more" applies to deer hunting as well, including feeders. Limit all forms of visibility of human presence and you'll be far more likely to get a shot at a nice deer. After all, they don't get old being stupid around hunters who are always after them in every way possible. Mature bucks become more reclusive as they get older and want to live out their final years in the safest place they can find. And this includes places with the least evidence of human presence.
