Be careful about the model numbers.
GoldTip XT Hunter 5575 doesn't really mean the arrow will work
for ALL bows between 55 lbs and 75 lbs.
GoldTip XT Huner 7595 definitely does not mean this arrow will work
for bows between 75 and 95 lbs of draw weight.
Carbon Express Select 200 does not mean the arrow works for a 200 lb draw weight bow.
These are just model numbers, LohGong,
and it's better to look up the stiffness bending rating on the arrow.
Easton has a very simple model numbering method.
Easton Axis 400 means the bending stiffness rating = 0.400 inches.
Easton Redline 690 means the bending stiffness rating = 0.690 inches.
Easton Fatboy 400 means the bending stiffness rating = 0.400 inches.
So,
best to look up the bending stiffness rating.
Easton 2012 (when easton uses 4 numbers...it's an aluminum arrow)
bending stiffness rating = 0.685 inches.
So,
aluminum arrow
or carbon arrow...
look up the bending stiffness.
You need to know the bow draw length setting.
You need to know the draw weight of the bow.
With these two bits of information,
software programs can figure out the total energy of the bow.
Once the software knows the total energy of the bow,
then....
you can pick a length of arrow
and
you can pick a stiffness rating of arrow
and
you can pick the weight of the target or field point up in front
and
you can pick your favorite vanes or feathers in back.
All of these things,
combine to create the "total stiffness" of the arrow.
The "total stiffness" of the arrow
must match
the "total energy" of the bow.
This may seem really complicated,
but the software makes it really easy.
When you get a perfect match
between the bow total energy
and
the arrow total stiffness,
you get really good accuracy.
