Welcome... I'm a little confused by your 129/11??? Are you taking 11 from Macon or 129? Are you doing this to avoid Atlanta? If so it will be slow going on mainly two lane roads.
Once 19 and 129 join together it's an interesting fairly steep mountain road with lots of curves and some passing lanes... last 25 miles.
I recommend going straight through Atl (non rush hour) on I-75 to I-575 at Marietta. This will get you to Blairsville on divided four lanes without any steep grades or curvy roads. 19/129 from Blairsville to Vogel is an easy two lane road.
This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.
