Well when the arrows were changed over the foc remained exactly the same.This is critical to keeping the tune the same.The arrows were definately heavier but the sight was changed from a target sight to a hunting sight so I did sight the bow in,but that isn' t a part of tuning.
As a matter of fact the last 2 bows I did were right on from the first shot with the broadheads.The other bow was a PSE that was about 15 years old.It was shooting 2117 with 125gr heads and I will have to say that one surprised me.The one I did 3 bows ago was not right on at first and the person wasn' t worried about it so neither was I.I new it was very close.
And if you want to use your term.An arrow carrying a broadhead will be more sensitive

to a bad shot than one with a field point.That is what makes the tune more critical with broadheads.If a broadhead is as near to perfect as possible,then most likely the field points will be very close.
All I' m really saying is if they aren' t hitting real close,then the tune is probably a little off.Or maybe the shooters form is a little off,in that case the form really needs to be addressed.
Too late with the bow.I already sold it to my brother in law that never has hunted with a bow.He hit the 2" circle on the 2nd shot at 20 yards.Yeah,the bow was a shooter.But never fear,the new cam 1/2 Ultratec seems to be surpassing the old one.
I' m starting to feel warm and fuzzy all over.
