Grand National has been ruined with the new trains.
Though, i'm pretty convinced that it's mostl due to them being new and unflexible. Old coaster trains flex with the track, these new ones don't. Maybe after they wear in they won't be so painful.
The lapbars lock further and further down throughout the course now. I wouldn't mind so much, but when they are down as much as they should be by ride-op pinning standard and they STILL come down further on the first drop, something's wrong.
And, Colossucks has clearly been ruined by the park. Those f-ing trains. Colossus has a boring layout and it's only good point was ever it's looks... but now oil spills down it's supports and it grinds aroudn the track liek nails on a blackboard. It needs new trains, desperately, to make it worth riding.
