Anybody have a better chart than Easton arrows are too stiff
mitch,Google Stu Miller's spine calculator and you can download it and put all the bow info in and you can get all the info you need.And edit the title of your post to spine not sine.Just click the paper and pencil next to the quotation marks on your question.
