I got some shafts off Ebay that turned out to be 3Rivers and they were crooked as the dickens too. A few had some pretty nasty kinks. Hand straightening didn't cut it. Had to break out my ol' arrow straightener - the kind with the lever and dial indicator for aluminum arrows. After a couple of sessions with that, they turned out to be good arrows.
I had never gotten cedar shafts that were as crooked as those were, andI would have been flat ticked off if I'd paid premium price for them.[>:]But, I only paid sumthin like $17 a dozen for them,so I couldn't gripe about it too much.
