I have a class that is filling up with booleans. Would it be more efficient to store these as a “set of”? I have 10 bools which is getting up there.

Sets need less memory as they are stored as bits.
Speed depends on the operations and amount of objects. I would recommend sets.

Same here.

Got it, thanks guys.
Btw, how can I know what the size in bytes these 2 options are?

You could use SizeOf(YourType) and output the values in a simple test program :)
