testing:: to finalize the choice of suitable letters

Testing the font styles, size and varying widths, on the actual size (200 pt for minimum size), to find a suitable font. I tested by printing out on the paper at full size. Viewer distance between 5 and 10 meter. From the result, 6 of 10 people were preferred the Helvetica Neue 85 Heavy (not capitals) / word space 25 than other fonts.
