Most difficult to get new WG/RG on oysterflex Daytona?

[SamArj]

Obviously I'm talking about the new model. Going by previous experience anybody have an idea about which of the PM Daytonas on Oysterflex would be most difficult to get?
As far as these goes I like all of them equally apart from the ones with diamond baguettes.

I can request one so I might as get one which is trickiest to get (if there is one) just so I can be a little bit more smug about my purchase lol.

Thanks
