Upload & Sell: On
I've very impulsive. Like a light switch. On then off then back on again. In a year or so I'll probably be buying them all over again
I treat my MF glass like vintage cars - they are fun to take out on a spin from time to time, but I am quite aware that there are more capable options out there. MF glass and this thread are also a great reason to just go out and shoot something, but you clearly don't seem to have a problem to motivate yourself to shoot pictures
Even though I shoot mostly AF 'when it matters,' I'm still looking to extend my MF kit (16mm and 50/55mm f1.2 mostly). Beyond that, any major lens investment in glass will most likely be a modern lens, with full DXO profile for perfect correction, and almost all of those are AF.
Meanwhile MF glass I have helps me stay sane by providing a reference of what used to be great - keeps me away from the highest end nano-fangled hyper lenses, as I can see in comparison that even my consumer AF lenses are quite excellent these days. But you certainly don't need a collection of really nice nikkors like yours to have that reference. Just keep your favorite(s) and take them for a Sunday morning spin once in a while
