What's the best way to land on a spinning asteroid?

I suspect that there are very few asteroids of the thousands and thousands
of known ones that rotate faster than what its gravity can hold. In fact the
only one that I know is 1998
KY26,
which rotates once each five minutes and is 30 meters across, so it has to
be strong enough to hold itself against an acceleration of 0.0001 g or so
(which despite being a ridiculous value would still be higher than its
gravity, I think).

IIRC, though, typically asteroids have periods of a few *hours*, resulting
in negligible centrifuge effect, and so using speed of rotation to find
strong asteroids would yield very few results, I am afraid.
