To Flip, or Not to Flip?

[Largoshark]

Hi TRFers. I'm in the midst of a quandary, and I'm hoping for some solid advice:

I've had my Sub 114060 for almost a year now, and while I have been fully enjoying my time with it, lately I find myself craving something a bit more unique. Ive always been drawn to the BLNR, and I'm on the list for one at a local AD, which I've been told should be available with in the next 2-3 months. Thing is adding it in addition to my 114060 is definitely not an option. I would have to trade the Sub, plus cash to make the switch. I just don't know if I'd regret it down the road.

Arguments for: date/gmt function, I love the unique black/blue bezel, I've grown to like the pcl's so much that I think I actually prefer them to the bcl's, although the glidelock is great I dont use it much (and never change it more than 5mm), I've tried the BLNR on once before and preferred the fit/case dimensions to the Sub, its more unique...and probably the main reason (although I told myself when I got the Sub that I wouldn't let it bother me) I'm getting tired of seeing the Sub on so many wrists every day.

Arguments against: Is the additional cost worth it?, sentimental value of the Sub being my first Rolex, the simplicity of setting the time on the Sub and forgetting it, the clean dial of the Sub, I noticed a lot of people on this forum seem to lose their infatuation with the BLNR and end up flipping it, while the gmt function would be useful it's not something I can't live without...and finally, my Sub has been accurate to the second since I got it (with some light self regulation)

If I do end up trading, how much should I expect to pay over the trade value? If it's over 2.5-3k then I will probably pass regardless (I have full set, box and papers, great condition)

One last option may also be to trade the 114060 for a 116710ln. Would be less of a hit monetarily, but I really think I'd prefer the BLNR if I can swing it.

Sorry for the incredibly long winded post, and for those that stuck with it, I genuinely value and appreciate your help. Thanks all!
