Good suggestions on here...
I would look at the Rossi Scratch FS, Volkl Karma, K2 Public Enemy, 4frnt STL, Armada AR6, Armada T Hall, and the Salomon Foil or Thruster. There are quite a few more brands you can look at too, Atomic, Dynastar, Line, ect...
When you say all mountain in Ohio, I am going to assume you might want to be able to "carve" on your skis when you aren't in the park. I wouldn't go with an ARV, MSP or a Big Mountain ski if you are looking at a true Ohio Ski, the turning radius on most of these Big Mountain skis are going to be a little too much for MRM or PNS. They still rip in the park, they just aren't going to do what you need them to do on 300 vertical feet. I love my 4frnt MSP's, but I don't think I ever have, or will use them in Ohio.
Start looking at your local shop, online, and if you get the chance, demo, demo, demo...
