I rode today too, 5 times in total. Did back row first early on, it was OK, had a bit of airtime and an insignificant amount of rattle. Did front row straight after and it was way better, with the whole ride seeming faster and the immersion into the misty tunnels being superb. Rode again later in the day and it had definitely warmed up. Did another back row ride which was much better than the morning, and two more on the front which were brilliant - certainly better at the front for me, this one. On my last ride I got some great floater airtime over the top hat and on all rides there were a few small pops of ejector around the layout. The hangtime in the two inversions is good, but the two launches are a bit underwhelming (though going into the mist is great!) I think I prefer the first half to the second personally.
The interactions with the other rides are great, the trains are lovely, the soundtrack is good but the theming otherwise is a bit tacky for my liking. There are way too many steps when leaving the ride - surely a bridge over the launch track would've been better? Overall it's a top class ride that is fun, not intense but very reridable. It doesn't beat Nemesis as best UK coaster for me but it's a clear second and just scrapes into my Top 10 for now. Most of all it shows up nearly all the other coasters in the park as being horribly rough and outdated. Infusion and Big Dipper in particular are no fun at all and The Big One is terrible after the first drop (which is still pretty great).
Queues were under 10 minutes all day and it was running 3 trains for most of the afternoon. What was interesting was when we were having a drink on the balcony at Coasters and it was running empty trains while they took the third train off, it was so quiet - such a contrast to the other rickety coasters nearby!
