I believe 3 fletch came about,as a result of folks gettin caught in a down pour.They still had enough layed down fletch with 3,or if they lost a fletch,they still had enough to keep em flyin.I use a 2 fletch,and group em with my 3 fletch,even with broadheads.I believe,that the key to sucessfull 2 fletch,is to have well tuned arrows.The big 3 fletch can cover up or improve untuned arrows,especially with broadheds.You get an arrow properly tuned n you dont need the whole bird on the end of an erra to get it to fly straight.
