Tough tough call between entry #3 and entry #4, with #3 currently having a slight edge. Like the use of blue and the sense of motion created by the arrow flying around the shield. Also like the use of the tagline "Secure Elegant Easy." Potential concerns, if we decide not to use tagline in logo, this one may quickly drop behind entry #4, which would be strong equally strong and recognizable without any text at all. Furthermore, this particular logo, if used in a single color (black for example) would lose some of it's power - the arrow would be lost in the shield.
Roger that. I want to come up with something that integrates the "v" as well. Besides, you're right...in grayscale it still looks fine, but in solid colors, loses it's pop.
Blackhawk - We still like this one a lot, however as this has evolved we've gravitated way away from the shield concept and we definitely are not going to use the tagline in the logo. Thanks for all your great entries. Look forward to more on this or future logos.
