A 66-inch hybrid longbow with lots of reflex/deflex would work for your draw; 68 inches would be better in my opinion. In a straight bow with a little setback like a Hill, you could probably get by with a 68-inch bow, but 70 inches would probably be better. Now a lot of guys will tell you they're shooting bows 4-6-inches shorter than this with 30 inch draws with no finger pinch. I don't know how that's possible. Regardless, drawsing a 60-62-inch longbow/hybrid to 30 plus inches puts a lot of stress on the limbs and riser. With today's modern materials, most will probably hold up, but a longer bow will just be more pleasant to shoot IMO. Good luck.
Oops. Just saw your update re self-bow. There I would definitely recommend a 68-70-inch bow for a 30-inch draw.
