If you read up on EIC, then you know what the triggers are thought to be. With the qualifiers you gave of what the dog won't be doing, many feel EIC is "manageable." Go beyond those parameters--dove hunting, for example, or training with pressure (multiple marks, blind drills, tight handling, etc.--in short, what the dog dealt with at the trainer's)--and it's my experience that EIC invariably recurs. But for a hunting companion, and with the hunter's awareness of what EIC entails, seems to be a good opportunity to get a nice dog that'll pick up his ducks.
