RE: High left tear?
What would concern me most is not the tear but the fact you can' t get rid of it.That is a sign that something is off somewhere.You should be able to achieve a bullet hole from any bow,even if it doesn' t shoot best set up that way.
Also,did you change the idler wheel when you made the cam swap?I am pretty sure that it needs to be changed also.
I have had the same problem as you with a bow that I hadn' t changed the cam on and I was also using a Trophy Taker.The problem was the arrow along with the cam being over rotated to pick up a few pounds.Spine will make a difference.Fall away rest don' t let you cheat and get bullet holes out of poorly spined arrows.
