The interesting thing here, is that MF is neither the most inverted [Chaos], air-filled [Magnum], or intense [toss-up] of the three that you rode. Indeed, if you felt bad after MF, it's just as likely that it was the straw that broke the proverbial camel's back than it is that it was MF on its own. I will attest that Wildcat has the strongest positive vertical and laterals Gs in the park [Maggie's got top neg verts]. It also has the strongest whiplash potential, which could be causing some of the disorientation.
And it's not like CP has a bad hang-and-bang like many of the SF parks...
