I still shoot my 20 year old compound bow for deer hunting. Still has the old hard plastic arrow rest on it. Anytime I buy arrows now I have to pull the knocks out and rotate so the odd color is facing out at 9 oclock when knocked. If I don't do that my groupings open up quite a bit. I feel like even if I buy a newer bow... I will still turn the knocks just because that's how I was taught and that has always worked for me. So as the others have said! TURN THOSE KNOCKS! lol
