Most situations you use your oGCDs on CD. Meaning, you don't hold them at all (the one exception is Life Surge...unless something happens to prevent you from using it on a BFB FT, always use it while BFB is up on FT) This includes Power Surge/Jump; always use Jump when it comes back, Power Surge to Jump (or Spineshatter if that's the way your CDs happen to fall) when you can...and obviously hold PS if you don't have Jump or SSD ready to go...
