Molly screw (expander) or Toggle for plaster?
Hello,
I have tried to mount my center speaker on a drywall following this method:

Currently, it is mounted with two M6 toggles for double drywall in a 16 mm drywall panel and one 5x60 into what seems to be a wooden stud. Yes, it is a 16 mm drywall panel on the wall, strangely enough!? I measured it by pushing a nail with a head.
However, I am not satisfied with how the toggle bolts set themselves, likely because they are too large so that the arms become claws that dig into the drywall.
So now I want to replace these toggle (molly) bolts with something else.
Regular simple M6 toggles for single drywall are noted for 13 mm, and by measuring the legs and the distance, I can see that the drywall will end just above the bend which may lead to two things. Either it will not open as it should, or it will open but damage about 2-3 mm of the drywall on the inside.

The other option, which is significantly more expensive, is the Drywall Anchor Toggle, which I unfortunately only found in M5. According to the store, they can handle the same weight and are often used when one has failed with toggles. The advantage is that the depth is adjustable, and you can be sure it will attach as intended. However, I'm not sure if the screw really ends up in the middle of the hole or how easy it is to remove it again?

What is the best option here?

Toggler is great but you can't reuse it if you make a mistake during assembly.
But if you drill with the right drill bit, there shouldn't be any problem with getting the hole in the middle, but choose a slightly longer screw so you can move the anchor a bit after you have screwed it in if it's slightly off-center.

Thanks, yes toggler seems very popular but I still chose to use metalexpander 6E as I previously mounted my TV with those. This version, which is made for single plasterboard, worked really well despite the unusual thickness of the plasterboard.
The important thing is to use an expander tool, it makes it safer to find the position where the expander has unfolded properly and also prevents tearing up the plasterboard when the sleeve wants to spin (with the screwdriver).
