Hey all. I'm building an airplane model and am having an issue with my poly cage. I have a crease running in a few places (two of which are shown in the example pics). I'm pretty sure it's because of the close poly-splits I did for other reasons but now I am having a heck of a time figuring out how to smooth them without making it worse by pushing in too far. I've played with selecting the edges or vertices and moving them, even tried using the soft-mod tool and sculpt but all are not giving the results I want . I even tried deleting some edges and that didn't do it.

Any ideas of how I can fix this?
