What tends to make things confusing Broth is that Head Scouting can vary so widely. Not only is there the ratings difference- obviously you want the best guy you can afford to increase the "truth factor", but then one has to consider the type of scout wrt his position on the tools/neutral/ability spectrum. I won't even go into all the other factors involved.
Since there is quite a bit of debate concerning these issues and subjects, it only compounds the problems. I don't think we typically come into any discussion around the boards with everyone on the same page. Look at practically any thread and a large portion of it consists of contributors asking Who, What, When, Where, Why and How...
just to get to agreement on where to start.
No wonder there are some pretty grumpy folks at times.
