I like your variations. I like the banner for Partners in #19 but not the "W" as much as the others.
I like the two tones for the name but the emphasis should not be on "Creek". If two tones are used, they should be for "Wit Creek" and "Partners" as the two separate parts (like #14, #15, #16).
Not crazy about the line between the "W" and the name on #17 and #19 but I am going to see if it grows on me.
Would like to see what Wit Creek and Partners the same size font and on two different lines next to the "W" symbol looks like.
Thanks for the great looking designs.
