Often the quickest replacement for an `unwrap` is an `unwrap_or` with a sensible default.
Other times where error-handling is important use a `match` there and then. And don't nest the arms of the match instead use the return of the match expression.
On the other hand, I found `try!` pretty awkward. Especially since quite often you need to create custom errors alongside it and can go down a rabbit hole in which you have to read confusing compiler messages from within macros about traits not being implemented correctly, and lifetimes missing, etc.
