Unfortunately, my personal experience is limited to the ONF South portion of the trail; I only got into this hiking kick over the last year. Before that, it was front-country campgrounds that I could get to via bike (hence my handle).
However, a great resource is Florida Hikes! (yes, the exclamation point is a part of that); they have several hikes listed in fairly decent detail on their website, including some on the FL Trail.
One of the great tragedies of the FL Trail, in my own opinion, is the paucity of actual information on the official website. I understand the reasons for it, but it's somewhat annoying from a consumer standpoint.
Anyway, if you have specific questions about the Ocala South section, I can help you there for certain. Elsewhere, well, I can do research, but it's not the same as having walked the trail.
