I voted re-grind, but it really depends on exactly what the problems of the individual razor are. From an aesthetic standpoint I like my edge to follow the spine, in other words the blade width is equal at all points. I also make the spine thickness equal from heal to toe. That way the bevel angle is constant for the whole blade. Any workaround will be there to deal with at all subsequent touch up or honing sessions.

Like Charlie says "I don't make mistakes, I just make smaller razors".
