Do all 3490s have the same spine?

[gpang]

Have been using the Cartel Spectra 3490 for my Hwarang:    http://www.doosungarchery.co.kr/eng/product/product19.php?ptype=view&prdcode=0909220064&catcode=280000&page=1&catcode=280000&searchopt=&searchkey=  

and have been thinking of replacing them.

Does anybody know the spine of these arrows as I cant seem to find anything on them?

Are they the same as the Easton A/C/C 3-49?

 i.e. Do all 3490s have the same spine?  i.e. Do all 3490s have the same spine?

You'll probably get some answers in Pow Wow. This is for shooting questions.
