^ You'll also know intemently how the thing rides, making it easier to guage the quality of your recreation.
But unless you enjoy such things, try to avoid rides with zillions of custom supports. I thought I'd cut my recreation teeth with a fairly small but historically significant recreation, a Jet Star III (Jumbo Jet). I didn't fully realize the support work this thing needs. I still open up the project and add a few supports now and then, and someday it'll be finished [sillyme]
