RE: Year-round dog.
I didn't see it on your list but did you check out Weimaraners? I couldn't be happier with mine. Just a great dog - incredible nose, great point, loves to retrieve, and a quirky personality to boot. He hunts within about 30 yds and regularly checks with me for direction. They have a reputation for getting really attached to their owners and therefore being very destructive when nobody is around. I think that comes down to the owner, though. I took the necessary time to train him and I have two cats to keep him company during the day so it hasn't been a problem for me. They crave attention, too, which is something you have to get used to. I read on uplandbirddog.com that having one is similar to having a child, and the relationship you develop is different than with any other dog, and I have found that to be true. Might be worth a look...
