For a wood coaster, Blue Streak is tops - hands up or down.
For a steel coaster, Magnum XL200 is my #1.
All of the coasters at CP are good - even the lame ones, like the Mine Ride (Woodstok's Express is better!) and Mean Streak, which is a beautiful coaster to look at.
If the Iron Dragon went as fast as PKI's Top Gun, if would be great.
If you're thin and short, all the others are ok. But, if you're like me - 6'4" and 280 pounds, don't waste your money going to CP. You won't fit on anything - and I don't know why when I can ride everything at PKI and other parks without any problem whatsoever.
