I think I am misunderstanding someone here.
 
If you have three components (RGB), then (with Planar Configuration==2) the
number of strips must be a multiple of three.  Michael's 6 strip
organization looks fine.
 
I don't understand what Chris is trying to say.  The TIFF spec explicitly
says that the red, green, and blue strips can be interleaved.  There is no
requirement where the data is on disk, just that the StripOffsets and
StripByteCounts must be segregated with all the red pointers first, followed
by all the green pointers etc.  The data can be anywhere in the file,
interleaved (by strip) or segregated -- writer's choice. 
 
What am I missing ?
