It is very much worth it, one of the better riding area's around. I would suggest you get to Marietta and pick up 16 just south of it in WV and follow 16 all the way down. The whole thing is very epic, one of mine and everyone else here's favorite routes. At the very least you MUST pick up 16 in Beckley and ride it down to Virginia.
No idea how much time you have but from Marion VA it is a not too far hop South West to Shady Valley and 'The Snake'. Not as epic as Back of the Dragon but a good run and lots of nice roads that will get you there.
Keep asking questions, there are a lot of us here that ride that area a lot.
