How do you reduce the spine of an arrow?

[mgompf]

I was given 18, 4560 Carbon Express arrows.
According to the chart on their website they should work for my 52# @ 28" bow.

However the spine seems to be a little heavy.
Is there any way to reduce the spine?
Add more weight up front, bigger feathers, add a footing to the front?

Any ideas?

Add wt up front.  Give some brass inserts a try.  Bare shaft them first if possible.

If the arrow is too stiff for your bow you need to reduce the dynamic spine by either a) increases the length of the arrow or b)increasing the point weight.  You can also go with a "faster" string on your bow, but that'll only get you a little.

Lots of good ways to load up the front end of your arrow and thus reduce the spine.

Thanks guys.
I will try getting some heavy points and see if that helps.

Every thing that was said above, plus

# move your strike plate in
# use fast flight string
# less strands down to 4 or 6
# reduce the size of your, string silencers

Each on of these plus adding weight to the front will weaken spine.

If there full length, just start out with them long and cut slowly, use the desired weight head you wont and tune accordingly.
