I have a friend with a GSP, I think you'll be happy.

I grew up with an English Setter, had one as an adult, and had another fried that had one. While you *can* get them to be a "close working dog" my experience shows that is an uphill battle (against their instinct). While I love the Setter, I do not equate them with "close working dogs". I think you made a good choice on the GSP.

Good hunting.....!
