I personally would hold off on Flash Passes until you arrive and assess the crowds. V2 is a hell of a lot of fun, not going to lie however the park can still be enjoyed without it.
^In all seriousness, the park is not what it should be. Period. Do they have an amazing coaster line up? Without a doubt! Are they doing everything they can to make general upkeep the norm? Nope! Will I still visit to ride TC? You bet your a$$.
I'm honestly not sure I could rank them, but if i had to it would look something like this:
1. Texas Giant, Outlaw Run, Medusa
2. Iron Rattler
3. Goliath
I seriously cannot separate the top 3.
Why did you put Goliath as #3? Just curious.
I know from my personal operational experience at XC that this is true. Difference in capacity with 2 trains isn't worth the greater chance of having a downtime.
1 train operation @ XC is the norm. 2 train operation is usually only during summer and Haunt. I don't mind the 1 train operation because it has less downtime.
