#7 is a good start because it reflects the design you did for us on Trek Global. Is it possible to make the loop on the image look like a b, but preserve the compass center and points? Also, can you drop the dots on the i's, and use a darker orange like #21?
#137 is very close. Can you try a variation for us? Can you drop the three points (triangles) and make the icon look a little more like a 'b' and stylized a bit more to look like a flame?
