I think I go with the presets. I division per 5 knot crosswind component, just hold it there. As you accelerate, you should start getting a broad idea of the actual crosswind strength from the amount of rudder needed. The aileron is already there when you need it, and you can start backing it off s you speed up. I think it's too late when you start to feel a wing lift- you are then fighting a correcting battle. As for spoiler drag, if it's lifted, minimal at low speeds. The spoiler's also helpful keeping that wing down. But there are many ways to skin a cat- whatever works for you! I don't think it makes an awful lot of difference, just it's untidy to have the aeroplane tipping over slightly.
