It would be awesome if the Route Finder search tool had the commitment grade as a search field. Especially when climbing in an area one isn't as familiar with, it would be sweet to filter out everything below a desired commitment grade, if you're looking for a longer route to do.
The "number of pitches" metric sort of works for pure rock routes that are listed as such, but it doesn't work for big alpine routes with mixed modes of travel because these generally don't even list a number of pitches (because such a metric would be useless; for example, Liberty Ridge, N. Ridge of Baker, Cassin Ridge, etc.).

Indeed! Luckily, anybody can make a route update suggestion to add commitment grades, or any other missing information, so it will be easy to sort that info out over time. Perhaps this capability would encourage people to be better about adding that field, at least for route where it is appropriate (i.e. long alpine routes).
