If you can't move the saddle back far enough, you may not have a setback seatpost. I haven't heard of anyone who couldn't balance on their saddle who was using a setback post and a saddle with normal rails, i.e. not a Brooks.
A few years ago I amazed my riding buddy when whilst going downhill and riding on the drops I showed him that I could remove my hands from the bars and keep my hands beside the drops without sliding or falling forward. He didn't know that was even possible.
