You yourself said that Innova is only SLIGHTLY superior to Harvest Blend. If you go about switching food over correctly, there is very little stomach upset. My Aussie has never let me switch him over "correctly" he will just pick out the new stuff after a couple days. He has a sensitive tummy too. I had my Doberman on Innova and I am in the process of switching her off of it. It's a little bit TOO good for her. Not all dogs thrive on the same foods. There is no one perfect food for EVERY dog.
Oh, I understand that no one food is mana from heaven... I'm an independent nutritional consultant, for the time being, and preach that day in and day out. Innova IS, however, in the upper echelon of super premium commercial foods, and I would rather the OP moved laterally rather than backwards. Perchance switching to Orijen, Nature's Variety/Prairie, etc.
