I would advise against it. I just don't think there is enough utility in it to make it work. If you have had the $20M in scouting for HS or College, you know those ratings are off, but at least they give you a barometer of where your players might land. The advanced scouting gives you the same thing -- a barometer of where a player might land. However, you still have the challenge of getting that player on your team.
I would suggest, if you don't already do so, keep track of past draft classes or past large INTL signings to see if you can trade for guys that way.
