There is no need to skip the Holmes County Trail between Brinkhaven (the east end of the Mohican Valley Trail) and Glenmont. When I rode through there in June 2012 on a six-day trip across Ohio, this trail section was one of the most memorable of my trip. While it may or may not be "officially" open, it is a packed cinder trail that is definitely cleared, maintained, and easily rideable. I have a 1995 Schwinn Searcher Express with 700 x 35 mm tires, and it was no problem at all. Indeed, the trail was markedly better than the muddy, rutted, overgrown Mohican Valley Trail. From the east end of the Mohican Valley Trail in Brinkhaven (at a Mail Pouch Barn), just go across US 62 on a lane past a pair of red oil tanks to pick up the Holmes County Trail. From Glenmont to Killbuck the trail is not completed, has missing bridges, and is closed, but SR 520 is not a bad road between those towns.
