Hmmm, after a careful review of my options and weighing the pros and cons of each removing either Curufin or Thingol, my vote goes to:
++ Thingol
Removing Thingol will eliminate Turin's father figure. There is also a high likelyhood that Melian will pack her bags and leave for Valinor, now that her precious Sindarin loverboy is gone, leaving Doriath open to attack by all kinds of unsavory creatures (like Orcs and the Sons of Feanor). Angst, angst, angst, for poor Turin!
