Mystery Mine has some of the worst transitions out there, but it's still my favorite, and that all comes down to the theming. The main drop and inversions are also decent.
Dare Devil at SFOG automatically comes in second, and that's all because of the lap bars. That being said outside the first drop it doesn't really do anything? Bit forgettable honestly.
Untamed is next. Pretty standard, bit shaky in a couple spots but nothing too bad. Looks nice too.
Saw comes last. Indoor section is great actually, but transitions outside are bad. Just an awkward layout.
Yeah, pretty sad that my favorite Gerstlauer is Mystery Mine. Their newer stuff looks better but I just can't get excited by any of it.
