Hmm, I'm the owner of 1 hyperactive, remarkably stupid (but noble) springer. Took him on as a much abused rescue dog - he's absolutely rubbish with other people, but is great when we're alone and tracking - he automatically goes into 'quiet mode' when I hunker down to look at spoor - we've just come back from Snowdon, and we managed to get within ~5m of 2 roe deer in thick woodland. However, beware of spaniels - they are very boingy!
