so why do you feel that linking to that category page doesn't sound good? It does seem to lead the user to a variety of products for that category that have more information of interest to the user. You even seem to be stating the user and the conversion metrics is good. So doesn't it all sound positive for the user and hence Google?
Well, it SOUNDS good, but again, it is all part of the mystery of why the (old) blue-widgets.html page stopped ranking for "blue widgets", then my home page stopped ranking for "blue widgets" and the new blue_widgets.html never ranked for blue widgets.
