After shooting at a certain distance, a heavier arrow would surpass a lighter arrow in distance traveled b/c the weight of the lighter arrow enables the air resistance to slow it down at a more rapid pace. The heavier arrow will continue to hold momentum, thus, it will continue to travel at a greater distance. So essentially at a distance of say...70-80 yds, an arrow with 30gr. moreweight, might actually have less drop for that ten yards than the lighter arrow.I could probably figureall of this out butI already have enough math to do everyday All of this is subjective to everything of course but physics says, what i explained is right

If shooting distance is your thing though, there is no need for anymore of our conviction for you to try and shoot a heavier arrow. Shooting targets is your thing, as mine, so you are more concerned with speed and trajectory 99% of the time. Hunting season though, i will have a totally different opinion b/c a small diameter heavy arrow will penetrate better. Thats all there is to it.
Hope your bow is easily repaired and back to normal soon,
