^True, however they could just use the normal clamshell style surely? By the looks of those pictures, the restrains are offering no support to the riders shoulders or chest, so why bother with the OTSRs?
I'd have thought for this ride it's something to do with the mounting points, not being able to make the restraint more like a lap=bar, however it'd be cool to see if they implement this technology and restraint type on a coaster style which would support lap-bar styles.
