initial placement notation

An average line of Arimaa notation takes 23 characters (including spaces) to write. However, the initial placement lines take 66 characters to write. This is visually imbalanced and takes an inordinate amount of space.  I know that the way the bots work makes this unlikely to change. However, here is a system that takes only 28 spaces:
 
1w Exx Mxx Hxxxx Dxxxx Cxxxx
 
The rabbits are omitted, because obviously they are put wherever there are no higher pieces. The disadvantage of this system is that you can't go through left to right and place the pieces as you go.  The advantage is that on paper it looks better and is still fairly easy to understand at a glance.  
 
Of course, it is possible to notate this opening move simply by listing the pieces in order left to right (e.g. 99of9: 1w RHDEMDHRRRRCCRRR), but I don't like this way as much.

What is it you don't like about this?  I find it to be the most instantly understandable by far (or maybe it would be better if there were a separator after 8, eg 1w |RHDEMDHR|RRRCCRRR|).

You're right. I guess in the back of my mind I was thinking that it didn't look similar enough to the rest of the lines, but now I've seen the light. I like the separators, too.

Instead of the seperator row numbers can be used:
1w 2RHDEMDHR 1RRRCCRRR
1b 7rhdmedhr 8rrrccrrr

Woh, that is a very good idea for changing the initial placement notation into a simpler format.
