Just being curious here.
Does anyone know what brand of fast flight string and how many strands are used in Easton's modern longbow chart?
Generally Easton charts have been on the stiff side,and they are just suggestions.There are so many different FF type strings these days.And then too not all longbows are the same,risers cut to center,past center and off center.And every shooter is different,there are just so many variables for charts to be accurate.
I don't know what they use but if you enter your bow weight about 5lbs less than you need it usually works out about aright if you are shooting a bow cut past center.If not centershot you need about 10lbs less bow weight to get the right result. jmo
This spine chart is the way to go. MUCH better than anything i have ever used
