That all rapids are not the same the same could be said that not places within a given rapid are the same. That is why I case any significant rapid worth it's salt. The concept of forced-choice comes to mind. One particular rapid comes to mind, the last rapid on the Back River that came after leaving Franklin Lake. It was long and nasty. After a long time examining we decided to cross the river, about a 0.42 mile. of boney rapids. But it was what was below it that was of concern. If we trashed we would be in deep trouble. We were on the outside curve of a rapid and ferried over to the inside of the curve. It would be a very long hard slog vs a short carry. on the inside curve.
