Arrows mathched to bows?
 

Is there any evidence that a certain brand/model of arrow will work particularly well with a certain brand/model of bow? And maybe not with another?

Say a split limb design vs. solid limb vs. parallel for example.

I know with firearms, some guns like a certain round/bullet weight over another byexibiting a more efficient paper pattern.

as long as the arrow is the right spine for the poundage and drawlength of your bow, any bow can be tuned and shot with any arrow as far as i know

I don’t agree completely with this. Some arrows do notfly as well as others. You have to look at arrow consistence with in a set of arrows. Like spine, weight, straightness and over all quality of an arrow. This all play a part in good arrow flight.
Now I would agree that if you use any good quality arrow that is spined right you should be able to get it to shoot well, if bow is tuned right.

It seems to be more that certain arrows matchspecific archers more than specific bow types.

There are a lot of reasons for this including (but not limited to):
- confidence due to past success
- availability of spine that fits an archer's DL & preferred DW
- brand loyalty
- sponsorships
- etc.

Here's something else I thought of . . . If cutting down the arrow increases the spine, then how do you know what the spins is after cutting it down. Is there some graph or mathmatical way to determine this?
I'm shooting 27.5" draw and arrows are cut to 28. Axis arrows. I was told that if you shorten the arrow, you stiffen the spine.(?)

RE: Arrows mathched to bows?
 

There are no formulas or calculations to determine spine.They have to be measured on a spine tester to show the arrow deflection.And yes..if you shorten the arrow,the spine will stiffen

RE: Arrows mathched to bows?
 

This isn't totally true.It is true that the arrows spine is measured on a spine scale but that isn't the end.

We need to know the DYNAMIC spine of an arrow to know how it will perform,or should perform out of a particular setup.Everything from using a d-loop to having an overdraw and point weight affects the dynamic spine.


There must be a formula for that becausealot of the charts ask for point weight but the arrow programs ask for all these details,I am not aware of what kind of formula or if they just figure some sort of % spine increase for fingers verses using a release with a d-loop.


Arrowmike is absolutely correct about arrow quality playing a factor.

My shortest post ever to follow this one.

NO

The formula is much more complicated than I am willing to figure out myself.

The arrow spines are calculated through on target software and are shown on a moving graph to dial in the optimum dynamic spine. Throw on a heavier tip and the pile weight increases on the aroow, effecting the spine greatly. Put on a lighter tip and the pile weight decreases.

I have used on target software for getting the exact dynamic spine match for my setup. It may require shooting a pound or two heavier or lighter than I wanted, but having the arrow dialed in makes a noticible difference.

Well, even if you do figure it out, mathmatically speaking,what exactly are you going to doabout it? You typically only have severalspines to choose from. If you cut an arrow down .5 inches then more than likey you will still have to use the same spine of arrow. With bows today it is probably better to shoot a stiffer spined arrow.

Besides, arrow chartscombine arrow length and draw weight to determine thedesired arrow spine. If you are between arrow spines I would personally go with the stiffer wall. To each their own ...

RE: Arrows mathched to bows?
 

If I remember correctly, the stated arrow spines are at 29 inches. So that means if you go shorter the spine is greater as there is less room to flex. If you go longer, the spine decreases. I will sometimes shoot a longer than needed arrow to get the arrow to spine out just right for my setup.

My spine is around a 440 and I can obtain that by playing around with the tip weights and the arrow length, all while trying to keep the desired FOC.

I found it alot cheaper to purchase an archery program which allows me to try different adjustments to my arrow and see the desired effects long before I even cut an arrow. The cost of the program that I purchased is alot cheaper than a dozen useless arrows......

AMEN

;)

RE: Arrows mathched to bows?
 

yes i do agree with you... i managed to forget that part haha

RE: Arrows mathched to bows?
 

My goal here is to buy some new arrows (leaning towards the carbon Express Maxima in 350), have it cut to my desired length, and maintain the proper spine for my set-up. I'm also switching back to 125gr heads.
