Well my absolute fav is the Vekoma SLC heart-shaped roll-over (and yes legendary, I have experience the 0-g roll on Hulk ;)) After that, would have to be Arrow boomerangs/B&M Batwings.

--who for some strange reason really liked the flatspins/wingovers/corkscrews on B:KF @ SFO.
By the way, as I know it, there are NO zero-G rolls on inverteds. The 'inline twist' is not really a zero-G roll as it is relatively flat as opposed to the parabolic shape of the zero-G rolls on Kumba, Kraken and the like.
