adding to winners makes much more sense to me than reducing from them
as such respected trading authors as Van Tharp, Tushar Chande and Michael Harris go to such lengths to clarify in so many standard trading textbooks, it’s an inescapable reality that taking partial profits means that your position-size is at its biggest exactly when your risk is at its highest, i.e. right after you’ve opened the trade 
you might want to think carefully about that, perhaps, before deciding whether it would be reasonable for you?
