The S-tier (not necessarily the one mapped out by ACA) from Jacksonville runs along highway 90. Ninety's terrain can be rolling, hilly, and relatively flat. It has nice wide sidelanes that are smooth. Trees and forests on both sides of the road can block off northwinds. There are many good places for stealth camping.
They are paving over an old railroad right of way to make a dedicated trail from Palatka to Lake City, roughly parallel with highway 100. It is still in the works, so forget about using it.
Stay off highway 27, also 27/19/98. In winter these roads are corridors of hell for a cyclist.
