The best resources for you may be at the library under the authors Dashew, Pardey, Moitissier, Knox-Johnson, Abei, etc. Each of them has insights that may be helpful in developing your own reasoned opinion. Each of them has taken the trouble to actualy do some heavy-duty sailing as well, before considering and writing up their stories. Their opinions may be worth more than people''s who jus happen to come across your query on the web.
