Aw man, I guess I gotta disagree. I think if you can be creative like pic related, it works well. I actually want to get back to building more rides that start fast and bleed off speed and finish off at like 20-30mph.
I like doing a twister spire chain lift to the top cuz it looks cool. Other than that, I like doing it to keep things compact or localized to an area. There's also;
>chain lifts on all track pieces cheat
>steep incline to top
I've seen that IRL, it's just disappointing that we don't have the graphics for that (or many other things).
