Looking for 10-mile Sassafras Hike

I'm getting ready to hike the South Carolina Highpoint, Sassafras Mountain, in a few weeks, and I'm looking for a 10-mile roundtrip hike. I had a map of such a hike at one time, but now can't find it. I think the hike starts at Rocky Bottom, but I can't quite remember. Your help and suggestions with this hike are appreciated...especially locating the trail head!
