Monse,
Thank you very much for your quick reply and work!
Of the three with similar design #2,3,&4 I like #4 best. I like the yellow that seems to catch the eye better and adds some additional contrast. That being said, I like #5 even better. I like the growth feel with the upward movement of the bars and the arrow wrapping around them, also moving up.
I do miss the shaking hands (from the simple thing I created, shown in my samples), but maybe by trying to include some remnant of them wouldn't work or look good. Just a thought.
