All of your designs are interesting and well executed. We picked #52 to be in the top 5 because we think your "HQ" has potential. We are looking for a logo that has an "HQ" that can work with the word "performance" but can also stand alone to be used for promotional use on sports apparel. The "HQ" should have a unique character and have a sports meets tech feel to it.
Though your designs are all terrific, we want to see more ideas specific to our company.
I managed to come up with some interesting concepts that are very bold and techy. The mark itself has a very sporty feel created by the dynamics of the arcs.
