After my visit today, all of the non B&M coasters are a complete mess. Colossus was doing about 350pph, one train operation, and sitting on the back row I could see visible jerks along the train which were subsequently painful moments later especially around the cobra roll, the lift motor doesn't sound very healthy though. Stealth had multiple closures throughout the day, but that may be down to heat. Saw was on and off similarly, being shut for a 45 min period at one point and seems rougher than on my last visit. The flats were working well though with rush on 2 swings and swarm was eating queues. Also the bag checks have replaced the ticket kiosks, so now everyone has to get tickets at the AP building which is a bit of a silly decision.
