Arrow spine software says “too stiff.”

[justin davis]

I’ve always shot pretty stiff arrows and think you can tune stiff arrows. I also think stiff is better for hunting. With that said how much faith do you put in spine calculator software?

I trying out some different arrows. Tuned them up and they shoot pretty good. However I ran my arrow thru archers advantage and it says “too stiff!” That’s with .300 spine arrow. If I plug a .340 spine in it stays optimal middle of the green.

Wondering if I shouldn’t go .340?

here is two screen shots of the software with .300 spine vs the .340 spine

If it shoots, it shoots.

Yea there’s different levels of shooting thou you know. My other arrows were weaker in spine and shot tighter groups and seemed to be more forgiving

I've always wondered about Archer's Advantage.

What did you put in for your "release type"? That seems to have a big effect on the final result.

I have used the software for a while now and always build my arrows on there before purchasing. I will spend a bunch of time tinkering with the software changing arrow brands and models, spine and components. I get all the specs I want with an arrow that spines just on the stiff side and I have been very happy with this.

Ok good to hear. I’ve never really tried spine software before

You can always err on the side of too stiff in compound archery.

Yea I agree. However seems like optimal can be better than too stiff. Reason I wonder is my old arrows were weaker. They were much more forgiving and more accurate and tighter groups.

Seems like a no brainer then. To your original question, I would go by the software unless the bow told me otherwise.

Apologies for not reading more closely the first time.

No your good. I’m just curious how accurate the software is. Aside from testing
Both arrows. I don’t know how the lighter spine would shoot.

I have just started to use software. Years ago I had a friend run stuff for me and what was supposed to be optimum in AA I had trouble with broadhead flight. I went back to running stiffer arrows and it corrected everything.

All my hunting setups show stiff or slightly stiff in AA. I'm ok with that. I have been playing with it a little bit, still rely on most of my old ways of deciding what to use.

I'm not great with programs and software, I'm more of a hands on type.

This is of course with hunting arrows, field points on the front it's a different story. I prefer to actually be a little weak. I kinda assumed everyone is on the same page with that, but figured I'd add it to clarify.

Ok thanks. That’s good feedback. Yea I don’t want to buy differnt arrows if “optimal” isn’t really optimal.

It hasn't been in my world, but your experience could be different. Some here get great flight out of stuff I would swear is too weak, maybe they are better at it than I am. Or it can be differences in bows and release as well. Face pressure plays a big role in it I believe.

In my experience, stiff arrows shoot well through paper, but rarely group as well as arrows that are spined appropriately. Stiff arrows are one thing I believe can cause a nock high bare shaft when the nocking point should be correct.

The easiest way to do it is get in the ball park with software or whatever you think should be right and start long. Cut off a half inch at a time and bare shaft tune from there. The more weight on the front, the more exact you will have to be.

That’s just my opinion.

Yea that’s what I’m noticing. Stiff arrows don’t shoot near as good as optimal spined.

Justin, what else other than spine did you change? Different brand/shafts? I've experienced that just between different manufacturers with the same stated deflection. I think spine consistency can be a significant factor.

A lot can be said for that. I have seen some wide variation on spine within sizes, tho I still wonder practically the difference between .368 and a .326. I think so long as they react in the same direction coming off the bow it's not that critical.

I haven't really played with it.

Matt- So arrows are same manufacturer. But two differnt kinds. Old arrow was a .330 spine with 160 grains total upfront. The new arrow is .300 spine with 210 grains up front.
The old arrows shot more forgiving and really tight groups. New arrows seems to not shoot near as tight of group and more finicky to form
