Trad goldtip vs black hunter goldtip spine?

[Bldtrailer]

Are the black hunter goldtip(3555/5575) shafts the same spine as the trad goldtips(3555/5575) (I know the weight is different) but do they spine/tune differently?

not sure about all of them, but the 7595s are definitely different. the black ones are .340 spine, and the trads are stiffer at .300


Big Jim just posted a thread the other day about how that was going to change soon, and that the .300s are basically being phased out, and all shafts will now be marked with the correct spine.

hopefully someone will chime in soon with info about the other two.

just looked it up. no variation between the two for 3555 and 5575

If you guys spine test your carbons they are very rarely accurately marked with the vast majority running stiifer than marked. Also depending the seam of the shaft I have measured as much as 11# difference in a quarter turn of the shaft... although that was not on a GT.
Every archer should own a spine tester and check every shaft to be sure of what you actually have rather than take a manufacturers word for it.

This is truth! ^^^^^^^

I spine every one of my GT XT Hunter black shafts (55/75), and they range anywhere fron low .340's to high .390's, with the majority being .360 -.380. I have probably spined near 30dz and have yet to come up with a single one that spines .400. And they have .400 printed on the shaft!

My purpose in spining every shaft is to get my shafts in like groups. I do not want a .342 and a .388 in my quiver at the same time.

This is an on going debate and I don't have the answers, but carbons don't seem to spine accurately on "spine testers". Doesn't seem to matter who makes them either.

Here's the thing though, I own a spine tester and no longer even blow the dust off of it. I probably go through 6-8 dz arrows a year...don't like to waste valuable time searching for missed ones and am never afraid to launch one in to a dangerous environment.
They shoot the same one way or another.
I would expect that very few people have spine testers and they only know what they have by shooting them.
Last year we sold right at 4000 dz arrows and I had maybe 3 complaints. One guy even sent back his "missed spine shafts". My tester said they were fine.
This year, it will be closer to 6000 dz and I can only recall a couple complaints.
One guy wanted his money back because he couldn't get 3555 heavy hunters to shoot out of his 37lb bow with his 27" draw...He kept insisting that the spine was off when in reality, there is no way that arrow would ever work out of his bow. But he kept telling me everyone he called said it should...whatever.

The difference between the woodgrain and black shafts is weight...except in the 7595's. More weight in a shaft will make it act stiffer.

Interesting observation, Jim.

I had corresponded with a chap who for years built custom arrows for competition shooters.  He'd go to shoots (both wheel and stick)and peddle his wares.  Those big money boys wanted perfection.

He spined and weighed every arrow. His observations were, regardless of the money, that nearly all carbon shafts, sold by the dozen, had at least 1 or more that were 'off'.

He kept separate boxes and eventually would get a matched dozen even of those which were "off".

True, you can't actually MEASURE spine of carbon on a static tester, but you can check consistency among shafts of the same pack!

You found different than he.  Carbons are my choice of shafting, but the more I read, the more I'm convinced they have to be monitored as well.

My last dozen had 3 that in individually tuning, showed a slight variance... but everyone's mileage may vary...

Carbon Express and Easton products usually do quite well on a spine tester in my experience.  Many guys will weigh carbon shafts, very few will bother to spine test them.  As Big Jim mentioned though,  carbon is a very forgiving material within reason.

It doesn't matter if they are spined as marked... as long as they all spine the same. This has not been the case in my experience and the stiff side versus the soft side of the shaft only compounds the issue. Regardless of its forgiveness in dynamic spine if the static spine isn't matched before tuning the arrows will not fly the same.

YES !

Like I said above, I spine all my shafts just to get groups of like shafts together.

In years past, I would have an occasional "flyer", just shrug my shoulders, and throw it away.

Since I started running shafts through a spine tester, I nearly never have any flyers.

That tells me that there was really probably never anything wrong with the occasional arrow I was throwing in the trash, but rather it was just dissimilar from the rest in my quiver.
