This is a good way to find out what spine will shoot best out of your bow first hand. We offer these test kits with 1 arrow shaft in each spine. 600, 500, 400 & 340. Sold with the inserts loose so you can cut to your desired length.
Have a length in mind? We will cut them for free. Please provide us with the length desired, measured from the throat of the nock to the back of the insert. After purchase you will receive a confirmation email, simply reply with your desired length to that email and we will cut them. Its that easy.
