Im a user of heavy hunting arrows.... like everything, it has its own set of advantages/disadvantages. My present hunters are about 700gr. Making up a light 3D arrow, I ended up with just under 400gr. Its a bust for me, because there is enough difference in trajectory/point of aim, that if im use to my hunters I shoot well high with the 3D arrows. If I shoot enough for my mind to adjust with the 3D arrows, my hunters go well low. In my case, there was just too much difference, and it takes too long for my mind to adjust. So, im opting for a bit lighter hunter in the 600gr area, and will use one arrow for both play and hunting. Id think a lot of variables would come into play per each individual and their set ups.
