You could also try tucking your bottom fingers on your bow hand under when you shoot. This may push the bottom of the bow over. I agree with the guys saying that there is a little bit of a mental issue here. Good job on the second place. Something may be working out in your head. It is alot better though if you can get the cant out of your bow along with the cant out of your head. If you want to take 3-D shooting to the next level you will have to be level. If you are canting it will be alot harder to get your second and third axis set on your sight. Sounds like you are well on your way.
