From what I've seen firsthand, the Deutsch Langhaar (German Longhair Pointer) is the calmest versatile breed on the planet (except maybe a Spin or Bracco). If DLs aren't calm, they aren't bred. They have always been known as the calmest of the German breeds and were purposely bred that way.
Of course they have long hair, but they only really blow their coats twice a year. Shedding is moderate the rest of the year. I can tell you that there is no way that my longhair sheds more than a lab
I also really like DDs. Most of the DDs that I have been around have been relatively calm dogs. I agree with Ryan in that the German testing/breeding system is often the way to go. Knowing that every dog for the past 100 years has had to pass the same 2 hunting tests ensures that the highest number of pups bred have the stable temperament to perform to a hunter's expectations.
On a totally different note, I do know of someone that has a litter of Braque Francais on the ground. These French Pointers look fairly similar to GSPs (very short coats) but they are supposed to be calmer and hunt closer. I have not had the opportunity to see either of the parents hunt, but having met them on a leash, they did seem a little more laid back.
On yet another note, I have not met a hyper BB so that could be a good route to go as well. If you can ever take a drive to Nebraska to visit Rufnit Kennels, it would be well worth your time.
Good luck and happy hunting!
