Which font cuts very clean in a small size?

[crafty too]

I am working on a vinyl project, and so far my smaller letters are giving me a hard time. Is it the font or is it Cricut? Is there a font that cuts good small? I need a small "blocky" font.
Thanks!

***I need it really small, like .5 an inch.

I haven't had good luck cutting smaller letters in any font. Hopefully someone will have some suggestions......
