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

I'd assume vehicle carrying people on this mission would have a docking module at it's c.g. which would dock at pole as you suggest. Believe we should just start boring at pole & store excavated material in containers we brought. If asteroid is 1km or > our bore tunnel could go away from axis & start to provide gravity from asteroid rotation for workers.
Still think we must put that mesh bag over outside of entire asteroid to assure asteroid doesn't fly apart from the boring. I think we should build whole first colony inside an asteroid as proposed in a 1964 book "Islands in Space" by Cox & Cole. Ed S.
