Lowering Stall

I'll need to find a site. Sounds interesting. Thanks.

Have you looked at those vortex generator tabs placed on top of
the wing. Very negligible top end decrease. They come in a kit
and are easy to apply. Users claim 5-10 kt decrease in stall.

Just for discussion, what opinions are there for an individual lowering
the
stall speed of an existing wing considering constructability and cost?

I remember there was some leading edge profile modification studies done
years ago but can't see that as a practical approach for an individual.

Thinking about how to add sailplane-type upper surface spoilers, WW2
fighters underwing dive brakes, etc.
