Carbon arrow help

[triggerfinger]

This roeum was namee arrowa, not primitive arrows, so if this is in the wrong spot feel free to move it.

Anyhow, I need some advice on carbon arrows from some more experienced archers.  Im looking to add some archery stuff to my show inventory to give me a little more diversity.  Long story short I found a decent deal on some carbon arrows but I am not sure how the spine works.  They are made in china and I dont know if they use the same type of spine system we do.  The spines they gave me were given in a colum named "deflection" and was quantified by a 3 digit number on the riight side of a decimal.  like .400 or .500

Also they are not as straight as some better known brands, they are +/- .006 or .008 inch.  Which is way more than the .003 i see here alot.  But i doubt that makes a huge difference.  Also gpi varies from high 4s to 11 gpi.  Im not looking to put on every arrow they carry, just like the 3 most popular.  Suggestions, opinions welcomed.


Also would you use an arrow or broadhead brandyou never heard of if it was 1/3-1/2 price of the more popular stuff.

Sounds like you need a spine tester, Solve the problem real quick for any arrow. 
As for the broad head, well just purchase a couple, and do your own testing and see how they hold up.
That's my 2 cents.

 I don't know? I shoot blemished Goldtips and Grizzley Sticks. They are 35/55 and 55/75. I think I'll pass on shooting a brand I don't know anything about, I've already been to the arrow "blowing up" party.

Hey look at this.  The top where is says easton spine is the deflection.  I know a 340 or .340 deflection is 80-85 spine.  http://www.3riversarchery.com/pdf/ArrowCharts.pdf

I shoot .600 out of lightweight bows like 30-45#  The .500 spine works well on my bows in the 45-55# range. I have some 400s that shoot good out of my 60# bow. Hope this helps.

Pardon the incoherent responses,. I'm on my phone.   Thanks for the help guys.   I'll check my out that site on the spine information.   I can't buy a few and try them out,  when importing you buy by the. 1000 and hope you made the right decision
