Take a screenshot, Whistler nor Cabo were never on BOP 5...At least not as long as I've played.
My notes state that the first version of Bo5 had two Cabo holes (##4 + 13 on the Bo5) plus two Whistler holes (##9 + 16). This version began with KIA #2, CCC #6 and OLY #17, then Cabo #2.
At some point of time, Georgian received the honorable task to create new versions of the Best-ofs (?w/o Cabo, Whistler and OAK?) which are active today. Bo5 starts with PBL ?#2?, CHB ?#9?, KIA ?#16? before the first Par5 on MER.
The descriptions above let me think that the old version is still in use in the H2Hs(?)
