What is the best grain-free food for a Labrador Retriever?

My lab is just about 1 year old and I am in the process of transitioning him to a grain-free food from Innova (we were told that the quality of Innova is expected to go downhill after they were purchased by Menu Foods) I am trying Fromm Surf and Turf, but am not sure if that is the best option for a labrador. Thanks for any help!
