k60 or k90

I cannot decide whether or not I want to buy the k60 or k90 keyboard. I have looked into both keyboards and they both look amazing, but I am a 3d game artist so the wrist rest is really important to me. Unfortunately, no store around me carries either keyboard, so I cannot test either of them out. I don't really care about the price difference, macro keys, or back lighting, the deal breaker for me between these two keyboards is the comfortability. Which one is more comfortable?

Thanks

I would suggest the K90 as it has the full wrist rest.

The K60's wrist rest only covers a certain area of the keyboard which may not be the best if there are shortcuts all around the keyboard.

well the full wrist rest is not what I am worried about. When modeling and animating all of the hotkeys are on the left side of the keyboard. I have looked at other reviews and some people say that the k60 is more comfortable and others say k90 is more comfortable. I am mainly just looking for which one has better padding. Right now I am leaning towards getting the k90 more for the laser edged keys (have seen reviews where the k60 fades pretty quickly) and then purchasing a separate wrist rest.

Thanks for the advise
