We really like #6 too. It gives us some elements to use elsewhere. Can you create the +2 element without the gaps in the + and the bottom of the 2? We also like the rounded "w" in "two" that you've used in #5. We think the PlusTwo is a little flat. Is there a way to add some color into the PlusTwo without it becoming too crazy? Even try a two-tone black and charcoal for the PlusTwo maybe?
Hi try lightening up the "marketing" a little more so it is quiet obviously contrasted with the PlusTwo. Also give us more contrast in the gray between Plus and Two.
