I was on the front seat of the train in the video Inferno Insane posted. It felt awesome, we were up there for what seemed like ages and the backwards drop was pretty cool too. I'm in 2 minds about Thorpe Park taking these measures, its a shame as you could predict when it would rollback and aim to get on that train, but I'm sure they will still happen occasionally, and besides you don't want it to rollback unless you're on it as it causes a delay!
