First off i dont want to be anywhere near you when youre shooting your bow at 68lbs with a 200gr arrow. Secondly, you need to get your stuff together before stepping into the woods. Thirdly Find a better pro shop that knows what they are doing, get the right arrows for your setup, if your fletches are tearing off then something is out of wack, what rest are you using? Get your bow setup by someone thatKNOWS what they are doing.
