I like 35 the best, can you use different colors? maybe even have the name in something other than gray/black. CLient likes lime and grey too, These seem a little to harsh in the density of the emblem colors.
onto something with the last one, although the colors are still not dramatic against one another. 57 & 56 I like, but the emblem is too much like feathers, and the client will not like that...plus it is an american tv station icon
