Didn't read all the replies...but as straight as possible or as you can get them....not sure if it was mentioned....
But a bent arrow will have less dimensional stability at impact and will bend to the bend expending energy to perform as intended as the weight of the arrow will no longer be behind the head to push...but will push to bend the arrow further.
Grain run-out and bare shafts that absorb moisture will not stay straight. Use the compression method, to straighten shafts them dip in a sealer. You can wrap with clear wrap if you are not finishing them. Lacquer and a clear coat will help keep them straight. Moisture content in wood shafts should be below 8% before sealing. Do not wrap tapered shafts tight, or they will be bent.
