#5 This is the logo that I like the best so far, I like the size and the angle of the swoosh's from the GM Solutions logo, please add the detail of the planet like the GM Solutions logo. Please feel free to add red as long as it doesn't overpower the logo.
#10 is nice and clean however, when we eventually get to a point of removing everything except for the half circle it will look too close to the Nike swoosh. Please re-create #66 for GM Solutions with the same color scheme adding "PRS" where there is currently "GM", add "Planet Rock Sports" underneath the logo.
