Im thinking of buying a fletching jig in the near future. I heard Bitzenberger is the brand to buy. can you adjust the degree you want the fletchings to be or do you have to buy each clamp made specifically for straight, 1 degree offset, or helical?

Which leads to this poll question.
Which fletching style do you prefer for hunting?
Im shooting straight b/c I didnt have a choice at beginning of season.
