Not a big fan of the H-that-looks-like-an-A logo with the ring. I get the concept, and I like the focus on the space theme, but it looks slightly over-the-top IMO. The H-star is the perfect blend of simplicity and yet being an easily-identifiable logo that makes a statement about the team and the city.
Other than that, my only gripe would be that I'm kind of tired of Navy everywhere. How about a more BLUE blue than a navy blue? White, Gray and Navy...75% of the teams in baseball have had phases of those colors. Let's find the balance between blending in with the rest of the dull pack (1990's uniform theme) and sticking out like a screaming sore thumb (Rainbow Guts).
