Well, I happened to like the last one.
At the risk of repeating what I already said on AIM (and sounding like an elistist prick), the Puttimon line would be my choice if the claim of said Digimon evolving from Solarmon were supported/cited (though Puttimon would make a fine Armor form for this Digimon if she's to be anyone's partner)...
So, I must give my vote to the Kudamon line, as well as my suggestion to make it an old-fashioned Bandai-style Kudamon to balance out Hang-chan's presense. :^,^: Kuda-Tail is a neat, canon and very logical evolution, and I was looking forward to the time someone used it.
On a side note, all of those sigs are marvellous. :¦D: You say my graphic skills have improved? Well, so've yours. That blonde Lilithmon in particular is an extremely impressive piece of work.
I like either Turuiemon or Kudamon.
