Help me decide!

[How]

Hi all!


I currently have in my collection:

- Sea Dweller 4000 (Ceramic)
- Speedmaster Moonwatch
- Tudor Black Bay Black (Rose Dial)


Suddenly, two pieces which I have been on the hunt for (for a few years now), have suddenly surfaced with opportunity to buy:

- 16610 Submariner, as-new condition, V-Serial
- 16710 GMTII Pepsi, pristine condition.

As beautiful as my SD4k is, I have had a hard time getting used to its weight and height on my wrist. Its bulk and heft makes me very conscious of it and it is no where near as comfortable as a Submariner on the wrist.

I Fell in love with it, but quickly starting to fall out of love with it. Hence it keeps on crossing my mind to flip it.

It's bad (or good) timing that two beautiful pieces present themselves to me at the same time, and now I am in a dilemma:

Shall I flip the SD4k, Moonwatch and BBB and get the classic 16610 Sub + 16710 GMTII Pepsi (that I have been on the hunt for several years now)?

What would you do?
