+1 on not asking in the Rolex forum. Youll just get told how crap the PO is and how to manage your life properly. Thats a tough decision though but if youre heading to a one watch person (something I intend to do at some point but keep failing) that PO has to be pretty good option. Setting aside the Sub being a classic, we all know this, youve got a modern classic in that particular model and its a little more under the radar than the sub. Its a close call though with that particular sub. Youve clearly got a good eye for the details. What about selling all your bikes to justify keeping both watches? Winter is on the way and you could live without a bike for a few weeks(days). Then treat yourself to a "little runaround bike". That would be my workaround. Although it wouldnt end up being a runaround bike but we will deal with that at a later date.
