I do not care which is faster.

Could've fooled me, based on your question. At least half of it is dedicated to talking about the speed... but I digress. :-)

I only care what is the best design.

If you want to know how other people feel about it, then I think the best option would be a design similar to the one chromatic described. But if you are set on using callbacks, then you can mark me down in the "argument passing" column.
