I am not familiar with those roads.
The Trail typically has gradients of 2% or less, I believe,but some are quite long.
This applies for the Trail in general EXCEPT....in some places between Rockmart and Cedartown,
where the Trail exits the RR bed and has to traverse local roads for a bit. From what
I have been told, there are some significant HILLS on that stretch.
Plus, going east past the 0 mile marker at Mavell Road, there is a pretty steep rise coming up to the shopping center on the East-West Connector. It is a DOOZY....but, short.
