I was given a dozen of Easton "Eagle" arrows size 2117. I can't find any information about them on Easton's web page. I am sure they are antique, but appear to be in new condition. They came in the original box. They are 31 inches long and straight fletched with 4 3/4" vanes, have inserts installed and have green flour. nocks glued on.

I am shooting 70# x 29 1/2 draw and am wondering if they are safe to shoot off my bow and if they are even worth the time to cut down to 27" and refletch?

They're an inexpensive XX75. I'm not at the shop, so not sure of the spining for that length and DW.

Thouse arrows are too weak for your setup , more like 55 to 60 lbs with a 28" arrow . 2413's would be a better choice depending on what weight tips you are useing .
