I thought you might have Brittanies, you may have mentioned it previously (on that other now-defunct forum). I've taken mine out for grouse before but other than two grouse up in NH as a 2 yr old we haven't met any success on grouse in Pa.
Mine isn't exactly classic or finished and it's no guarantee he'll even retrieve the bird for me! He's so jacked up over finding and flushing, many times he'll be sniffing for the next flush before the first bird even hits the ground after the shot! He's got good instincts and a helluva drive to find birds. Unlike many bird dog hunters I've met though I'm not concerned with perfect flushes and retrieves. If he's eager and finds the birds and flushes them, I don't mind picking them up. He's obedience trained but everything else he developed on his own, even following my whistle & hand signals from great distance. I just started putting him over birds and he took off naturally from there!
I hunt in a club with several guys and some really nice, finished labs, golden retrievers, spaniels and some high-priced pointers. The first time I brought my Lab to hunt within the group nobody was expecting much and were apprehensive at having an "untrained" dog hunt with their dogs. We had two finished goldens and two supposedly finished GSP's plus my freebie Lab. This is no exaggeration, my dog put up the first 4 birds within an hour, catching one by the tail feathers in mid-air, and by the end of the hunt he and the two awesome little Goldens ran circles around the two overweight and expensive GSPs. After that, nobody has ever shaken their head at the thought of hunting behind the big, goofy Labrador named Fish! Some of the guys actually check to make sure I'm bringing him!
He's hell on the farm-raised pheasants but I always wanted a chance to hunt him some place like South Dakota over wild pheasants and see him work.
