Some of the Six Flags free spins may be different each side but not in a predictable way -- for example same number of fins, just diff. spots. It does definitely keep rocking between the fins and it could be a hill that actually flips you. I seem to end up upside down right at the point of maximum G force at the end of a raven turn.
Didn't ride any of the new stuff yesterday though. Was going to circle back around but TT and Grizzly opened at or after 4 and then I saw I305 running. Timbers may have been my slowest ride ever and Grizzly seemed a bit smoother than late last year but also could have been just slower. They really could have moved yesterday an hour later, it was just getting right during the last hour. FoF and Tumbili were about the only things running when I arrived at 2, followed closely by Anaconda, with Dominator just starting to test. Woodstock, Backlot, Racer and Windseeker never opened.
