Last grouping, first one on top left. Since your company is new, the name is the most important thing right now. Once you get your name out there then the peripheral logo design can be nailed down. I also agree with trying to stay away from red for the same reason stated. (even in power point, never use red when talking about numbers).

IMHO the triangle to the left creates a cleaner look, while still showing your name. Plus it also offers just that little bit more of space when you use that as your letter head.
