Explain how you can breed the nose out of a dog??
The fact is good FT and HT dogs must have excellent noses!
They must find birds in heavy cover. They must also be able to use their nose to find bumpers. They must also be able to distinguish the bird they are looking for from all the other previous areas where birds have been and the smell of the birds that have been carried back.
The facts are that good field trial and hunt test dogs make excellent hunting dogs. 90% of people don't understand what these dogs are capable of.
Of course if you took a dog that's only competed in field trials out hunting one day he's not going to be better than an experienced dog that's been on hundreds of hunts....however, give that field trial dog a few hunts under his belt and he could be amazing.
