If two events followed one after the other, I would use the Perfect Continuous:
- Finally we found the path we had been looking for.
But, if some time have passed after the first event, I could use the following sentences, right?:
- Finally we found the path we looked for.
- Finally we found the path we were looking for.
However, I don't quite understand what context should be for each sentence? Could you tell me what would make you choose one or the other sentence?
