I like the direction you are going with entry #18. Could you simplify it to AR Automatic and make the gate more stylized? I like the red and black. Thanks.
#24 Could you try making the AR offset (A a little higher than the R", remove the AR in the text and use a different font for the "Automatic". The columns need to be a bit more simple and stylized. Not quite as simple as the #26, as I'd like the columns retained in some fashion.
