Strickers but it's hard to get as they're only open a couple times a year. I'd try to do Indiana Beach and Holiday World if you can, both about 4 hours from the two parks you mentioned. That or Kennywood which is 3 hours from CP in the other direction. In just a straight line from KI to CP though....I think the only things with wood coasters are Strickers (medium sized family wood coaster with the most ridiculous drop ever, kids wood coaster) and Jungle Jacks (kids wood coaster). There's also Coney Island Ohio in that area which is a beautiful park with a lot of flat rides but the only coaster they have is a Pinfari Zyklon (although it's pretty good....has some ejector airtime in the second car on a few of the drops).
