I live the simplicity of #4 a lot, but I don't like that it doesn't have the actual name of the company. I don't like #2 because it is not balanced I like #1 because it is very simple, clean, balanced
I like the direction you're going with #8, but I'm a bit confused as to exactly what the logo is representing. I wonder if it would be beneficial to add some arrows at the "tips" of the shapes, to imply that data is flowing between different sections and systems.
Does the figure-8 have any significance? It looks like it should look like something, but I can't tell what it supposed to be. I understand the arrows, but I don't get the shape.
Sorry, I'm being kicked out of Logo Tournament by a group moderators that have problems with other people winning contests they're participating in. I hope you get a great logo for your MSP. Best regards :)
