To all you 29er's out there!

Is it a good idea to have a saddle on a mtb that's slightly more padded than a road saddle? I'm thinking of swapping out the stock one that came on my rockrider, and have a specialized toupe that I could use, but was wondering if it would be a bad idea to use such a hard saddle?

I have a really shit saddle on my 29ers, it's definitely not comfortable on a road bike, but on my MTB, I didn't really notice any comfort since I rarely sat down on it.

I don't think it's that important to worry about padding.
