Can I use any fletching that is 4" in length and real close to the height of the fletchings already on the Cross Bolt? Should I remove all the fletchings on the Cross Bolt and put all the same brand names on it? Should I remove all the fletchings and put something different like length and/or cut on my Cross Bolts? Should I throw my Fire Bolt away? (NOT

Also, I'm sorry I'm asking a question that has probably been answered somewhere else in the forum, but I'm just not finding it.
Any help would be appreciated.
