Some Advise and Opinions Needed

[Rolex Freak]

Hello All,

I wanted to hear some opinions and get some advice on the following. I've primarily switched my collection to all vintage. I currently have a red sub, explorer 1655, sub 5513 and a recently acquired 1675. In addition to this, i have a modern panerai 512 and a sub 16610 v serial. As of late, I've stubbled on a beautiful 1680 in excellent condition, with mint original dial. Now the question is would you sell the sub 16610 to make room for the 1680? I wouldn't want to keep both as i'd end up with too many subs for my liking. I'd like to hear what some of you have to say. Thanks in advance.
