200g vinyl, more static?

No. But I have noticed there's no correlation between mass and quality

Unfortunately true.
Still some of my better quality records lie in the land of the flimsy flexi flyer!

But we are now comparing original quality techniques, mastering and pressing with today's shambles.

Not apples to apples by a long shot.

Oh and to address the actual thread topic.
I honestly cannot say that I have really noticed any additional static due to the vinyl being 180 or 200g?

But I traditionally do not have much of a static issue at any time so may not be the best judge on that score.

Static charge sits only on the surface of an LP.  Since 200g LPs have the same surface area as do any other standard size LPs, I see no reason to expect that 200g LPs would carry any more (or less) static charge than those of standard size.

Seems I'm not crazy...

"Record players and records are particularly susceptible to static for a few reasons. Firstly, in the vinyl material itself, it has a very suitable medium for the buildup of static charge and ironically, the thicker and purer the vinyl used for the record (in the pursuit of better pressings, lower noise floor and higher quality perceived or actual), the worse the issue gets. This is why some 80s pressings that are thin enough to read through and pressed on vinyl that has feels more like recycled bottles is less prone to static build-up than some of the rather lovely pressings on sale today"

The additional height of a 200grm may insulate it more from static discharge.
