Skylon II was my favorite trainer. I got the Saucony Mirage to try out because the Kinvara did not fit me well. To my surpise, the Mirage is much less cushioned than the Kinvara, and thus feels more responsive. It is considered to have some support, but feels neutral to me. It has for me a fit similar to what I remember from my Skylons.
I am recommending it to those of you missing the Skylon.
