Dr Jack RAP and NAM were sufficient and quite good when I was flying in the midwest. Flying in Williams, Sierra, and Utah this summer, I find only the high detail rasps have the needed information. In particular convergences and cu vs. blue areas don't show up on the usual Dr. Jack scales. It would be great to have nationwide RASP. Thanks to the volunteers who put together the WIlliams, Sierra, and Utah rasp models.
