What Is The Easiest To Skinn/retexture?

I just wonder what you guys think is the hardest to skin ;)
I think that the hardest is to find a good armor texture for small foot units!

Hardest or easiest?

well, like this:
guys vote on what they think is easiest...
then i can see what is hardest by seeing what got the fewest votes :D
right now i see terain is a biatch and heroes are ez ;)

I dont really think this is the best way to know what people think is hardest to skinn...
mainly because:

1: very confusing title/post

2:why don´t just do the poll like;what do you think is hardest to skinn?


but I don´t know...

i say UI, its a 2d image
