A Dilemma

Cabled cardi progress?  Excellent.  Both sleeves are done as is the back.  I'm very near completion of the the left front as well.

Here's the problem.  There is a very deep v-neck that requires gradual decreasing beginning at about the half way point of the length.  This decrease is now at the point where it is cutting into the cable pattern. Having never done this before, I'm a bit confused.  At what point do I abandon the rope cable?  If, say, one stitch is missing from an eight stitch cable, do I just knit the seven stitches or do I cable with just the seven and give it up the next time around?  Which would look better?  The cables repeat every eight rows.
Just thinking out loud here.
