You are right, those definately are corkscrews. But also, they're not your typical Intamin ones, like on Fahrenheit. They are narrover and higher, and they have a longer leadin, and a shorter roll itself...
And by 0G roll, I was referring to any roll, that has/is supposed to have 0G at the top, and as far as I heard, the rolls on maverick pull around 0G. That might also be completely wrong, I really don't know, I've never ridden it.
That Tatsu wingover really does look similar.
Also, RCDB calls the element on Blue Fira a twisted horsehoe roll...
