Last I checked Bobby won Euro X...so it appears it worked for him there.
Again...it's a contest...not an edit...he has a run that has worked for him, why would he change it before it doesn't work for him.
Tom's run is also the same...the rails are different (but so it EVERYONE else's rail section since the rails are always set up different)...Tom does right cork 9 blunt, switch left dub 10, switch right dub 10 (if there's a 4th jump he adds another dub in)
Bobby's run is usually right 9, then 4 DIFFERENT variations of dub12s (left and right, and usually a switch dub misty)
Every athlete does basically the same run (for both slope and pipe) and usually just tweaks the rail section depending on the comp.
