This thread is about bronze pams in general, not specific models, so there isn't much discussion or nuance here. More a thread about impressions and experiences with photos than facts. For facts, you need to look for threads of discussion about specific models and factories.
Also, the members here showcase individual builds and models purchased many years ago, so when buying a new one from TD, you need to focus on availability. So, for example, only VSF can be available for PAM382, and then to a limited extent, so discussion on this issue should be removed (Although VSF will be better than ZF, both in the proportion of the case and in the applied movement, also, it will be a different shade of bronze ).
I would recommend that you select the models you are interested in, check with TD, and if there are several options left, then look at the profile threads of these models and make a purchase decision.
In any case - good luck to you!
