Ive been using a new " kidney " shaped seat since just before the worlds in italy last year & wouldnt go back to the old shape ......The reason being , with the shape that the bag is, its a lot easier to form into a kneeling style roll & is more versatile as a seat in general then the usual round types in my opinion .
