It’s worth the money. The spring is usually cooler than temperatures associated with the summer months. This cooler, spring temperature makes the stings constrict a bit more than they would during the summer. The reduced effective tension that results from 15 – gauge string is offset by the cooler temperature’s constricting effect.
