I'm not too sure about the "Clover" look on #48 and #46, but we like the Spade designs. I think #49 is very interesting, it makes me think about a potential "BOOK" type with more pages, and the current design being the cover of the book, but a bit more open with different layers inside it.... sort of saying "WE KNOW EVERYTHING" and we are "THE BOOK" on this subject and industry...
See if you can play with it... Thanks
