On some level I like all of your logos. but the color scheme is the same and not working for me, also the choice of hearts or butterfly, is very specific and not for our Network. You have a good sense of Drama, out of all of them I think #23 is your strongest. If you felt like refining one I would start with that one. Remember that an ad network is still a network. Review NBC, CBS and ABC logos. Simple, but graphically strong, sometimes less is more.
