If you go to the Easton web site you can download spine charts and arrow selection charts free. They will tell you all you need to know. Grains per inch, total arrow weight,and if you put in all your info broadhead weight, arrow weight and fps it will give you your kenitic energy. I'll find the link and post it.

FWIW, a 2018 arrow cut to 29" with a nock and insert but no point weighs 391 grains.
