Done a few in OB as well and agree, you never really know what you're going to get. I agree with Jen although not just because they are an outcross every time. I personally believe when you start breeding for things other than brains, health and (or) conformation, you start getting undesirable traits more frequently.
Bottom line in my mind is that really good examples of either breed would not be used to create these types of dogs, so it's not very likely you would be able to get a consistently desirable result. No on is taking their best hunting poodle and their best hunting lab and making mutts.
