Arrow spine testing with points

[bccalls2011]

So I just started bare shaft tuning and was wondering if you guys use field points when spine testing or have tried shooting just the shaft itself ? Also what do you guys do if the flight changes after you fletch the arrows ?

Thanks again guys

You should study this information and follow it to the letter.Yes,of course you shoot with field points.Point weight greatly effects dynamic spine.You should be shooting both fletched and bare shaft arrows together,as you tune.Tuned correctly,there will be very little difference after fletching.There are ways to tweak things if there is a slight change.Read the tuning information.
