I have to agree with dakotashooter2, in that trying different set ups will give you your best answers. Sometimes useing 4 fletch does not work well with certain rests. Feathers work well with most rests and stabilize the arrow better. The fewer number of blades and lighter weight broadheads require less fletching coverage. If you use a trigger release, you can get away with shorter fletchings then if you shoot fingers. Plastic vanes are wheather proof, but are heavier than feathers. The speed of your arrows will determin what size fletching you need. I worked part time in a laege archery shop for 12 years when I lived in Michigan, and although it could never be explained to me, if you fletch your arrows with a left hand twist, they will spin faster and will stabilize your arrows better. I checked this through a chronograph, and it is true. But I can't explain it either. Starting to test several different set up this time if year will give you pleanty of time to figure out what will best suite your needs best for this fall. Good luck.
