I have some BlackhawkVapor arrows  some are 3000, and some are 4000 anybody know the spine on these, are the 3000 stiffer spine.

My experience has been that the 3000's shoot like a .400 spine arrow, the 4000's are a .340....

Good arrow...not the most consistent carbons out there, but killed a bunch of critters with them  

I have a whole bunch of 4000's that are bit too short for me now or else I'd still be killing stuff with them!!

Thanks Guru, if you what to unload some that's too short I'm always looking for a deal, lol

Blackhawk Vapor spines:
2000 is a .500
3000 is a .400
4000 is a .350
5000 is a .300
