If you are talking about not feeling they are that well-matched personality-wise, that's a whole different can of beans.
I love what they have, or "don't have", depending how one sees it. It's one of the things which makes them different and unique, at least to me. I love different Pairs for different reasons. I love S&K first of all for their outstanding SS and for their dynamic when they perform. I love the fact that they are not "cosy" or "romantic", if that makes sense?
Not that there is anything wrong with it, mind you. My most favorite Pairs have always been the classic Russian Pairs who oozed quality, class, elegance and "romance", for lack of better word. But these two are different. Tons of class and quality, but also more sharpness and attack in their perfomance.
