For a flusher, springer or lab. For a pointing dog, Drathaar, German Wirehaired (ducks and geese, wire haired dogs handle the cold better then a shorthair), pointing Lab if you want to train it to point. I like flushing dogs. In the book Hunting Dog Know-how, by David Michael Duffy (a journalist, who worked into training meat dogs) it is stated one can shoot more birds over a spaniel or flushing retriever with less work.
How far do you want your dog to work from you? A pointing dog works outside of gun range or has no functional advantage over a flusher. Both can work inside gun range it's just the pointer will be doing flushing dog work so why not use the Flusher instead? I had my pointers (English and red setters) working at 200-400 yards (a long shot for an 06). I worked my Chess at 20 yards. I hunted more with the Ches than the pointers because I liked hanging with him more. I've gone to a Jagdterrier now for the same reason. This is what you need to decide, which breed are you going to like hanging with? Having me tell you what is the most logical dog is only telling you what I'd say if I were in your situation. Choosing a breed is a personal choice. Go look at some dogs work at a few hunt tests and decide which you like. You may end up with a Flat coated retriever (a good duck fetcher and upland dog) or a curly-coated retriever or a spinone or an Airedale. You have to find the breed and individual dog you like.

PS Notice I haven't told you to choose a Jagdterrier. They are special dogs and take an experienced trainer to get the most out of them. This is my choice and I don't want it to become popular and get screwed up (re: Irish setters, Labs, Goldens, cockers, Jack Russells ect).
