Reliable was drawn with a somewhat dry brush, and then carefully made into a font. Reliable differs from other brush fonts, because it has got 8 different versions of each letter!!! 8 different letters that cycle while you type! Not really random, but enough to make it look very random!

And, of course Reliable has got a full load of diacritics

So, the conclusion must be: if you need a cool brush font, use Reliable!
