Might be you got 70lb limbs when before you had 60lb, but if that is the case it should not be hard to pull, I think that when the limbs were replaced that your timing is of causing it to be hard to pull, I had the same issue with my Guardian
there is a part on the cam that is shaped like a J, the bottom part of the J should be about 1/8 of an inch from the edge of the limb if this makes sense, may be some one has a picture and can show you if I didn't confuse you.
