Take this with a grain of salt as I might not know what the heck I am talking about. The high tear should go away when you move your nock point down. If it doesn't, I think you are having some fletching contact. Check to see if your rest arm is dropping when it should. When does the arm raise during the draw? It should just start to raise an inch or two before you hit your back wall. If it is raising too soon, that may be your problem. You'll have to adjust your cord.

The left tear is the same thing my brother has a problem with. He is torquing the bow to cause the problem. It may also be an arrow spine problem. The new string is probably shorter. I think this increases your poundage which affects arrow spine.

Again, I might be talking out of my butt on this. Hopefully someone else can give you better help.
