Hello, I'm not familiar with either of the feeds you mentioned as they aren't available in my area, but I am very familiar with hard keepers and my experience says if you've found a feed that gets a good result stick to it. Having worked in many facilities over the years any good one won't mind feeding your horse the way you prefer. You can always buy your feed in quantities that will last longer if multiple trips are the problem. The average horse may do just fine on most any feed, but if you've had problems in the past I'd say better safe than sorry. Hope the move works out well for you.
