There are any number of changes one could make to it, but without knowing anything else about you I don’t think I can confidently make prescriptive recommendations on the matter. By default, I’d run the program as-is to see how you respond, and if you feel you could benefit from swapping out some of the supplemental deadlifts in order to benefit your sumo pull, you’d be able to make a more informed decision at that point. For many of the sumo dead lifters that I coach, we still keep a fair amount of conventional pulling in their training until they get close to a meet.
