So let's just assume the LD riding bug has bitten and there are google maps heading in all sorts of directions and crazy things are being planned out.... Is the Centreline 24 still a valid (certifiable) option with the reintroduction of 130kph limits in NT? I'm also interested in the extent that other certifications could be nested within the Centreline ride - notably SS1600K, SS2000K, BB2500K, BBS2500K, BBG2500K, and could you nest the Centreline within a SS3000K?
