bigpapascout,

When an arrow is too stiff it isn't able to absorb the energy because it has leftover spine.The arrow will kick to the right for right handed shooters,just check the Easton tuning quides.I think they know a thing or two about arrows,bows,and tuning.


It is true that you can get an overspine arrow to shoot straight but usually at the expense of centershot.


I am not contradicting myself but rather giving tolerances for reference.You can't go 10 sizes up on the spine chart and expect a bow and arrow setup to tune very well.On the otherhand,you can go 1-3 sizes up and still achieve a decent tune.Broadheads require a slightly stiffer spine setup than a field point but you are not overspining, you are getting the proper spine.Basically,there is more room for error to the stiff side than there is to the light side.


Yes, hard cam setups require stiffer spines than soft cams but you are not overspining ,you are getting the proper spined arrow.



Dave,your setup seems to be at the breakover point between 340 and 400 so it is a good idea to stay on the safe side(stiff) with your setup.You should be able play around with 125 gr points to see if you like them better.That will weaken the dynamic spine a bit and MAY make a difference in the way the arrows perform for you.My honest opinion is that the arrows are ok but rather a tuning problem is to blame.Or the nut behind the string.


BT shooter not a problem,I enjoy helping when I can.I haven't been posting much lately because I have just been too busy with the kids and such.
