Cold, wet, humid and windy sounds to me more like the environment for a top-quality synthetic jacket, that would cost less. The jackets you cited are more for cold-dry conditions. A friend who uses the "Puff-ball" jacket (probably not enough loft for your climate) and says the new synthetics compress quite well. If always windy, you should also consider the weave of the outer material and its wind-proof ability. Is there a reason you are not considering a synthetic?
