Went again today, and rode 13 again obviously.
I went into it with a completely open mind once again, just tried to forget what I thought about it on Sunday and tried to see if I could pick out the good stuff. I also did something today we didn't do the other day, and that was to ride it up the front. The actual rollercoaster part of the ride (the bit before the drop track) seemed a bit better up front than at the back, riding up front suits this layout more. That said, it was still a bit rubbish
I realised today though how good that backwards helix actually is, don't get me wrong it's nothing particularly great but it is a laugh because of the undulating banking. Still well under powered though.
My overall conclusions are that it is a decent family coaster but then the theme of it negates the "family" element. I'm not saying that I hate the coaster or anything, but there isn't a coaster at Alton Towers I would rate lower than Th13teen.
As a side note for Mikey: It was raining today, full on, not just "greasy" in the air and yet the tyre lifts worked perfectly. There was more noise with the rain, but it wasn't actually a squeeling sound and neither was it very loud, you could only hear it from the train. It sounded like... hmmm, you know if you step in something sticky? and then you walk on a tiled floor? Yeah, that sound.
