i shoot 3 feathers, some times 4", sometimes 5". I dont notice any difference between them at hunting ranges but on the longer ranges at the target range the 5 has more drag at the long shots. I've also noticed that if I shooting good that day, it doesnt matter too much if I shoot chocolate chip cookie feather out or in so most of the time all my feathers are the same color unless I am getting low on my bright colors then I will fletch with a dark chocolate chip cookie feather to stretch the bright colors out. I will normally make sure I'm shooting chocolate chip cookie feather out but if I got to get a arrow on the string quickly, I dont worry about it.
