You have to pick:

Well, being a werewolf would only happen every 28 days or so...

you also have to consider what version of werewolf? twilight? True Blood? traditional? etc

Twilight werewolf. Control over turning. Though you imprint like ducks uncontrollably onto lovers[or babies]and get really sick when that person dies.
But you also get a tan. And land that's all to yourself that the white man can't do shiz on.
