Who will succeed and who will fail?

I already know that this fandom is currently going nuts over the latest episodes elmination, but let's try to put that aside for a bit and answer this question.

Jade and Isabel both have Idols, and knowing Disventure Camps and Total Dramas reputation for it's immunity idols, I think that one of them will succeed with their idol, and the other will fail with their idol and likely get elminated.

Who do you think will succeed and who will fail with their immunity idol, and Why and How?
