I'm not sure you need to change ladders. Making big saves, however, does make you look good, it's remembered, and it might mean that at review time you stand out and get the biggest raise.

At the time, I was the highest paid person in my group, so I didn't have anywhere to go. In other jobs, I've made big saves and it's helped me get a raise a couple times when I've asked. Not necessarily right at that moment, but at a time not much later.
