My SO is an experienced frisbee golfer so I referred your question to him; he recommends Innova discs. He says the two popular distance drivers out there are the Boss and the Valkyrie; many of our friends use the Valkyrie and like it. He uses an Archangel as his distance driver. The TeeBird is a fairway driver and so it won't go as far; he had a TeeBird and hated it because he couldn't control it as well as he liked. He would not recommend it; he says if you are looking for a mid-range disc that will fly straight, the Leopard is the better choice. He says you're going to want to look for a disc that's between 169-180g.
You've probably already looked at this, but just in case you haven't:
