Interesting thread!
The answer is Phoenix but since everyone is saying that...
Magnum XL 200. A bit rough sure but honestly it's not bad, esp if you know how to ride (I thought all enthusiasts knew tight belt loose bar, it seems not) and maybe it's weather dependent, when I rode this year it really wasn't bad at all. In back row ya get some nice pull and there's pretty intense airtime through the bunny hills. It's still fun and for me top 6 or 7 at CP
Besides that, hmmm yeah prob Beast, though it was better than I expected it still wasn't mind blowing. I personally was let down by the Kennywood Classics. Though I appreciate the history none really did much for me as rides.
EDIT: D'oh! I can't believe I forgot the Schwarzkopf's! Scorpion at BGT was pretty darn intense, and I can't lie I used to Lazer at Dorney RIP
