Is any MODEL info on your shafts? Other than that, I found this: from: http://www.outdoorsmenforum.ca/showthread.php?t=17417 fourth post down from top. Blackhawk Vapor 2000 Spine = 0.391" ASTM 6.20 gpi -------------------------------------- Some maths for you: 0.391"ASTM X 0.825 conversion factor = 0.323" 26#/0.323" = 80.6 pounds 'old' AMO --------------------------------------- BUT! other places I've read say it spines at 0.500" ASTM = 63 pounds AMO and then that it also comes in at 35/55.
Isn't the ambiguous world of carbon shafts a hoot?

All right, I'm going to attempt a readable format again.

Blackhawk Vapor 2000 Spine = 0.391" ASTM
6.20 gpi
Some maths for you: 0.391"ASTM X 0.825 conversion factor = 0.323"
26#/0.323" = 80.6 pounds 'old' AMO
other places I've read say it spines 0.500" ASTM = 63 pounds AMO.
=63 pounds AMO and
other places state it's 35/55 pound range.

Gregory, either take them to an archery shop and have the checked, or send me one and I'll check it for you.

Actually I'm looking at a Blackhawk 2000 and the specs that are printed on it...Vapor Hunter Series by Blackhawk...2000 ACA all carbon arrow...200=35/45. I still have quite a few of this shafts I got from Sispey River when he was in business some years ago. I've shot these in bows from 45# to 50#, fly great.
