#9 is a nice incorporation of the S and a lock. This is the one with the highest potential. Although, if you remove the "road" on top of #12, I like it. The lock incorporated into the "A" is a very nice touch!
With #33, can you make the "unlock potential, deliver results" a bit smaller? It is quite large right now. And maybe do those words in the blue you used in #9. Both are a great start and based on feedback are some of the favorites right now. THanks!
