Well your arrows seem to be the right arrows for your bow, but your centershot still could be off. I had a pro shop set up my bow a few months ago and they messed everything up, not all pro shops are created equally. Sometimes nock point could be off too. Its hard to tell with out seeing the bow. I would try to make my centershot around 13/16 or 7/8 and see what happens, also put a level on the arrow and see if you nock point is correct. Modern bows are so temperemental even the smallest error can spell disaster. Also, you said your using a trophy taker, if your shooting broadheads make sure the broadheads arent catching on the shaft rest that comes with the rest that you glue on the riser shelf. I had a trophy taker rest and my broadheads hung up on that thing a few times.
