Toward the end of this Saturday's puzzle I was all solved except for a region like this on the left:



After the initial trial/error solve I looked for a logical solution.  The best I found was:
1.  Try x above the middle 3.  With Fix Position and endpoint counting, this leads to a big loop on the right, contradiction.
2.  Try down from the lower left of the middle 3.  Fix Position and endpoint counting leads to a fairly quick contradiction.

Are there any cleaner ways to finish up this puzzle?  In particular, any ways that don't require Fix Position?  Thanks.

First rule out a the line continuing upwards from the diagonal 3s (it makes a loop), then a line on the left of the 1 above that (an odd number of lines enter th right-hand region).
