What is wrong with shooting an arrow with too stiff of a spine for your bow set up?

Thanks.

Nothing I can think of:wink:

Depends on what your purpose is...

The string on release could bind up slightly thereby affecting the follow through of the string. A properly spined arrow will flex a bit allowing for proper string travel.:wink:

Do you have a specific bow
and a particular arrow in mind?

A touch stiff can be a good thing
and give you some options for tuning it.

A touch weak is not a good idea
and not something I recommend for most shooting,
except in the case of a super lightweight 3D arrow.

Add an arrow wrap on the back end of a slightly weak arrow,
and now you have an arrow that gets you close to
the 5 grains per pound of draw weight limit,
and is just stiff enough to shoot well.

Like JAVI says, it depends.

It stands to reason that a perfectly spined arrow shot with perfect technique will yield the desired result more often than a poorly spined arrow shot with the same technique.

I am new to all this, thus my question.

I shoot an 06 Trykon-29 DL @ 65# (probably will increase to 67-68 soon). I currently use a Redhead Carbon Maxx 6075 arrow at 350gr total weight.

I was looking to change arrows (the above seem fine and have had no problems). I bought the OnTarget software to help me out here, but some of the "matches" for my set up only list either too weak or too stiff a spine......with no "good" match. I figured too weak of a spine was bad, but couldn't figure out if too stiff was bad also.

I want to find one arrow that I can use for both target (informal) shooting and hunting (wild hogs and deer). I also wanted a lightweight, carbon arrow similar to the above.

Thanks.

if you like a lighter hunting arrow, carbon express CX300 3D selects should fit you well. They spec out at 8.2 gpi. Throw on a 100gr head and you'll be sitting right around 375-400 gr for a 29" shaft. That will put you a touch under 6 gpp. You'll be shooting fast, but still a fairly heavy arrow to stick through a deer.

Thanks,
Rick

I should also state that the current shaft length excluding the nock is 27" (set up this way by 2 different pro shops- isn't this a little short?) and 27 1/2" to valley of nock. I use Blazers and 100gr FT/BH tips. My total arrow weight is consistently 350gr w/in 2gr.

bluz,

What are you trying to accomplish by changing arrows then? You're already about as light as you can go 68 #/350 gr is 5.15 gpp.

If they shoot fine right now, why not keep them?

Thanks,
Rick

Here is a new arrow spec....spines in the middle of the green for you

Hello bluzman:

You cannot pick an arrow simply based on the grains per inch weight.
You must pick the correct spine, which is why OnTarget2! works so well.

When you click the equipment tab,
and select a 2006 Hoyt Trykon, you also need to specify the percent letoff.
The default white box says 65/80.

If you don't do anything, the program defaults to the lowest letoff %.

I assumed you are using the 80% letoff.
Just go to the white box and type in 80.



I have selected the GoldTip XT Hunter 7595 shaft.

I have assumed 68 lbs of draw weight and a 29" AMO draw length.


GT XT Hunter 7595 shafts
Cut the shaft to a shaft length of 29"
(not including the nock or insert)

Use 100 grain broadheads or field tips

Use 2" Bohning Blazer vanes
(Use a full sheet arrow wrap)

I assumed a 15 grain peep sight,
and a 7 grain d-loop
and a 7 grain nocking point.



Estimated velocity = 282 fps
6.207 grains per lb of draw weight

FOC = 7.27%

74.46 grains of kinetic energy


This should work quite well for you.

>>but some of the "matches" for my set up only list either too weak or too stiff a spine......with no "good"

On the search filter options, uncheck the box marked "Selected Brand Only". Leaving this checked causes the program to limit database searches to only the manufacturer currently selected by the "Brand" combo box.


>>I want to find one arrow that I can use for both target (informal) shooting and hunting (wild hogs and deer).

Check the checkbox labeled "Both". This will split the difference in shaft spine recommendations that the program makes. Checking the "Target" checkbox will make weaker shaft recomendations and checking the "Hunting" checkbox will make stiffer ones.


>>I also wanted a lightweight, carbon arrow similar to the above.

Check the checkbox labeled "Carbon". Deselect the others. If you know a weight range for the completed arrow you want, check the "Weight Range" checkbox to activate the weight range filter. Use the up/down controls to change the weight to 350 to 400. This will locate only shafts matching your spine and within a given range of weight. The program will assume a shaft weight only unless you also select the radio button for "Complete Arrow" in the Find Matching grid.

These are the default settings...

Switch yours to look like this...

Thanks guys.....this is the input I was looking for....

I will make the changes to the database as recommended.
