Banshee was definitely #1 for me (not sure how many rides, but I rode it 3-4 times each day I spent at KI).
While Banshee isn't my favorite, it had a quick line and it's a fun ride!
Banshee was closely followed by Firehaw .
For some odd reason, when I went to Kings Island, Firehawk didn't seem to have a very long wait. In fact, most of the time it was a walk-on.
Also, I haven't been on this site much lately. With school, band, and having a job, I dont have the time.
