From my compilation of last season's quads, Reynolds, who actually had an injury, attempted 4S in every competition, landing two 4S and one 4S+3T with +GOE. Brezina (+0.29) and Fernandez (-0.43) also landed them at the World Championships which saw many successful quads, including the only successful, and beautiful, quad (4T) from Kozuka whose 2 others received -GOE. Joubert did his best there too, having landed only another one with +GOE all season. (I don't know if he has ever landed a 4S.) I joked about the special ice in Moscow.
I don't think Amodio has a quad of any kind ratified. He talks about having 2 quads in practice but, as far as I know, has never even attempted any in competition. His coach Morozov has deemed them not necessary or ready. We might see them in the new season.I think Florent Amodio and Brian Joubert have also had them ratified.
I don't think Joubert has a 4S either. Somebody may set me straight.
