I have built several coasters in the style of OL:FOF, Joker's Jinx, Poltergeist, etc. They really aren't too hard to build and usually get some pretty good ratings. I have seen some of these coasters online where the builder used the "launched shuttle mode". I don't do that. I like the capacity of being able to run multiple trains. I still use "continuous circuit mode", but right out of the station I line up about 15 booster sections pumped up to max speed (58mph?) to get the coaster into the "bowl".
