what is the stiffest carbon arrow of a reasonable weight? thanks,
Craig

I'm not sure if they're the stiffest, but the Gold Tip Big Game 100's are right up there.

The Gold Tip Big Game have a .280 spine and weigh 10.6 grains/inch. Aside from that, the Easton / Beman ICS Camo Hunters in 300 would be next. They weigh right around 10 grains/inch.

Speed pro max arrows are the stiffest arrow out there, they come in 5.5 and 6.2 gpi, if you use carbon already you could pick up 10-20 feet per second over what you are using, the down side is that they are extremely expensive and if you shoot stumps they'll break

CT Safaries at 15+ grains per inch are pretty dang stiff.

Dany is right, the CT Safari's spine .200 and are very straight.  No need to add any brass inserts or weight tubes with them.  If there's something stiffer out there, I never heard of them.  This result was after putting everything on a high-end spine tester, not my usual backyard testing!

njstykbow can you please tell me what the outside diameter is on the CT Safari ?

Where do they carry them  ?

Thanks!

Torben,

They're a standard 5/16" OD.  You can get them from Lancaster Archery Supply or check the sponsor's classified with KTinAK.  Very nice shaft.
