I apologize for not getting back with you sooner. If you're still interested in my entry, I can show you a black and white version, if the rules of this site permit it?
I understand your concerns of the rectangular shape. I think it works well being higher than wider and further conveys the "High Yield" part of the company name because of it. I don't believe the shape would prohibit anything; though it may require some creative thinking if specific applications have too strict of requirements regarding sizes.
let me know. thanks.
