I have an Ideal, and I love it. Although it did take a while to get used to - having been used to riding in a saddle without any knee role, it puts your leg in a great position, but feels v different to a normal saddle! Lucky you....
I don't like the K2 at all, sorry! I find it very uncomfortable and although it is supportive for jumping I find it restrictive and I hate the way the seat feels.
