None of these give any indication or concept of any of the elements of the project. Too generic and is the quality I could go and use an automatic logo generator for $10. Doesn't look like much thought given to these examples or did not read any of the description and use in the designs.
#7 was better. Focus on FIRST and showing some speed element with the swooshes in the "F" ....some other examples / variations of this concept would be nice
