difficult decision to make

[rootbeer7]

I caveat this post by saying I hope I won't need to sell either of my watches, but if I have to sell one which should go; a Tudor Big-Block, or Great White 1665, both full sets and great condition.
1665 will sell quickly and easily and I will have extra funds, the Big-Block may take longer and would cover what I need. In the future neither would be easy to find in the sets and condition I have currently, particularly the 1665, which I believe to be unpolished.
So, which would you say goodbye to if you had to let one go?
