Right now I think we have reached a point where unless someone comes up with a radically different type of bow we will see slight improvements every year that for the most part will not be enough to see a major gain from one year to the next, but when you compare what improvements are made in a 5 year span it will be substantial. We will see faster and quieter bows, we will see advancements also in broadheads and arrows also, that will happen slowly, but as with the bows, comparing what is 5 years old to the new will be a major difference.
