I shot the HCA speed pr arrow the other day and it added over 30fps to my bow.. The arrows are 5.5gpi and made of carbon.. does anyone have any feadback on them?
check your total arrow weight to mke sure you are at 5 grains per pound of draw weight if not then you are to light and risk damage to your bow.
I don't have any experience with them, but a friend who shot them said that they were not as durable as other arrows. When you go so far one way on the design of anything, you will give up something else. They chose to make these arrows very light so it's logical that they would have to give up on durability. He said that they shoot as well as other arrows, but no longer uses them. As zip4644 posted, be careful on total arrow weight vs. bow draw weight.
