This is not a criticism but merely an observation regarding the content of the initial post. Having read the post, I gather you are referring to fishing the open seas. And if this is the case then I am not going to contradict you. On the other hand, if you are paddling/peddling a lake, bay, estuary or a river, then I think a sit on top kayak is far more user friendly than a sit in. I have both types of kayaks and it is my experience that the sit on top, both in terms of comfort and ease of casting a fly rod, then my Hobie wins hands down.
