cm scale <weenie>rools</weenie>

I use the cm scale, because you can fit more on your game board, and
because
the metric system make a lot more sense than imperial.

Then again, in Australia we use the metric system for everything else so
I 
guess I may have a slight bias. 

On an unbiased not I like the way FT refers to units, rather than inches

or cms. If you wanted to you could use 1/2 inches, or something that
appeal
in principle.
