We got Chesney from a race horse trainer and he was very high in energy. Even being fed just pony nuts we could not get him to settle at all, even on hardly any food, but then by doing this we found he lost too much weight. Then I found Simple System and there were so many positives to it: cheap, wet, Chesney liked it, and also I could feed him as much as he wanted as it didn't make him hyper. With this feed I found he put on weight and I could then do my endurance, SJ, x-country and eventing on him. I even managed to hunt him on this feed and I would never have been able to do this before. Now I feed my whole yard Simple System and they all love it - I would never go back to any other feed.
