@yeslek Mostly because they do harder SBS jumps than other pairs teams. When they do SBS 3Ts she's generally clean. The troubles come when they try the harder triples like 3Lo - which she does cleanly sometimes but not others. But maybe that's why no other pair's team tries that jump SBS.
They do tend to have more problems with throws and lifts usually.
Have they ever done SBS toes? I can't recall them ever trying those, but I could be wrong. Ashley was always more of an edge jumper even in singles. Tim did SBS toes with DeeDee, but I don't recall Cain/Leduc ever doing them.
