I might be confused about what you mean and may end up looking silly saying this, but it seems to me that a LDC is easier to set right because an LDC is sort of set in a fixed position lengthwise to the mount bar. Mine at least are held in relatively fixed position by their shock mounts except for angle of rotation and where they are placed on the mic bar.
A pencil SDC can slide back and forth in its mount making it a bit harder to consistently space the right distance and the right angle in addition to angle of rotation and where they are placed on the mic bar.
