It's not bad except for the section immediately south of the first toll booth. That section is likely the most windy section you will encounter. The stopping every 20 miles is a PITA but I think they finally go on board with ezpass.
I did read recently where I-77 Northbound in VA. is going to have some construction that may hinder a return so you might want to check into that.
My last trip on the WV turnpike was Northbound in my Mini Cooper and the section I mentioned above was my favorite place to drive until mr. police officer thought I was having too much fun. (in my defense --- well, there is no defense I was flying through there) . I paid my ticket a few days later and now tow the car behind me at a nice steady pace.
