For the time, effort and cost, I would suggest you just winterize it and don't worry about it. Having just done my first "winterization" I support the other claims that it really is about $10 in anti-freeze and 10-15 min of effort to run it through your lines.
Come spring, fill up with water, run your lines, and you are good to go.
