trying to figure out how to get past this.

I have tried both, smooth and rigid binding, but it keeps grabbing part of the head when i rotate the shoulder bone.
Anyone know what's causing this I have tried a few different options under each binding and still the same. anyone gone through a similar case where the binding binds more than u want it to?

Create two new bones running at a 45 degree angle from the top of the head sideways. If you place them correctly, it will solve the issue without monkeying around forever with skinning.
