Winterizing: blow-out vs antifreeze for longer term storage?

You will need to remove the pink anyway.... why not sooner than later?
As long as you are not putting water in this would seem to be the best method.
Actually blow out the water first, pump anti-freeze, then blow out again.
Probably save the anti-freeze as it will not get much dilution.

This from a person that has never winterized :R
