I talked to the pro shop guy and he looked at my arrows and spotted the problem right away. My nocks did not sit in the arrow right, they were the old shorter style nocks that only contact the arrow at the front end of the nock and the back end. He said theysometimes wont sit perfectly straight with the arrowand lean a little. Looked at both cracked arrows and the nock did not sit flush with the end of the arrow. He said my new bow may have just had enough extra power to do it.I got the new nocks that are a lot longer almost twice as longand keep contact with the inside of the arrow all the way down. They said that this would fix it, I guess it was kind common with the old style nocks.

I could be under spined but due to my short draw length I am on the border of the 3555 and 5575(on the Gold Tips chart) So my spine SHOULD be ok.
