Ok alot of people seem to think my arrows are to stiff, but I beg to differ. ok there gt xt hunters cut at 28" with 225grs on the front, so you add more wieght to the front and it makes them softer, I am getting great prefomance from them they fly great , and are consistent, Now if ya look at the easton arrow chart , for my peak weight and draw length it reccomends a 400 shaft, and that is what I am using, so why would you !@#@$ change it. my draw weight is 51 lbs. I get tight groups with them and they work, so I just do not understand why others seem to think there to stiff, I am just going by what the chart says , and it says 400's so .....they fly straight and hit hard...there!!
