JParanee..Jason and Mike are proponents of lighter arrows for deer...and that is what i hunt....So Jasons recommendation was a 400 fmj cut at 28 1/2 " with a 125 grain tip. No trimmimg no bareshafting no pointloading.Mike likes the weight to be throughout the arrowshaft because te paradox recovers much quicker. That is what i bought and they are darts, with any broadhead. They weigh in around 460 grains but they penetrate much better than other arrows i have around and tried. Will try and chrono tomorrow if i can....
