Here's my take on the logo. I decided to try and combine the 'U', the horseshoe, and the technology of your products into one design. It's a high-tech horseshoe. Let me know if it's working at all.
Thanks. I think the diamonds are too big. Go with three of them, to represent each division of the company. Look at the gradient scheme used in #10. I like that a lot. Can you make the U/ horseshoe bigger and overlay unitas sports?
