Personally, I think the single biggest problem with the ride is that with the drop trims, it's too doggone SLOW. I'd like to know what problems CP had with the ride which prompted them to slow it down so much: too rough on the ride, or too rough on the riders. We know it was (and is) too rough on the riders, and the solution to that problem is laughably simple, though not at all cheap: get that foam crap out of the trains and switch to a properly upholstered seat, as we see on Thunder Run down at Kentucky Kingdom. In my opinion, that would nearly eliminate the 'rough on riders' problem, and the only reason I can think of that CP hasn't tried it (apart from the cost of re-doing the train) is if there are also maintenance issues with the ride. But nobody at the park is talking.
It is true that the PTC trains are incapable of navigating the curves on that ride, but coasters all over have demonstrated that the PTC trains will handle those kinds of curves if the wheels can slide...that is, if the track is lubricated. I don't think it is necessary to junk the current trains, but a bit of a rebuild would go a long way.
