Well, stuff is routing over Geant in v6 because Geant do hardware forwarding, while Janet are still doing software forwarding. Geant have a pretty M20 while Janet are stuck with a GSR. The extra hops aren't really extra hops per se, you have to go through the same boxes in either version, it just shows up differently.
