IK HANDLES APPLIED

IK handle is awesome in the many ways, but when it comes to me, it is a big trouble. I didn't really want to apply to my model, but I wanted my model to be bit more flexible on animating process.

For three fingers, the very top and bottom fingers IK handles are applied from the top and end joint of each fingers...

For the middle one, still the same but in addition, one more IK handles between the top joint of that finger and the wrist.
