That sure is a good looking boat....Ullman or Glaser....
Paul, I modified my spin retrieval line to come up through the grommet for the mast rotator and like it a lot. You mentioned getting it in front of the rotation control lines as being a problem. I found one more problem (easily overcomed): I did not fully untwist the line when I rigged it and it tended to kink up from twists when setting the spin (the kinks would catch on the grommet). Make sure you "unwind" the twists when rigging.....
Probably a rookie mistake.
