I will try to keep my ratings as open minded as possible.
Blue Streak-B+- Classic woodie with great air time(better before the seats were changed)
CC mine ride-C+- Average family coaster with nice theming
Corkscrew-C-- As stated before, it is an Arrow
Disaster Transport-C-- The only indoor coaster I know that can't run in the rain
Gemini-B+- Very fun and very overated
Iron Dragon-C-- Boring, but a nice change of pace/starter coaster
Magnum-A-- Without this air-time-machine there would be no Millennium Force or Goliath or anyother coaster from the hight/speed race
Mean Streak-D-- Just skip this one FOR THE LOVE OF GOD!
Millennium Force-B-- The First drop itself will get a B but the rest of the ride is actually pretty boring
Raptor-A+- I just can't get enough of this ride, great drop, great intensity, great hellix, JUST GREAT
TTD-A- One word AMAZING!
Wicked Twister-A-- This ride in the back seat is tough to beat
Wild Cat-B-- This thing is really fun, don't skip this kid-coaster it's a gem
Woodstock-C+- Fun kiddie ride that the adults can enjoy too
So in all CP's coaster lineup isn't quite as solid top-to-bottom as advertised, but it still holds 3 of my top ten coasters.
