I'm trying to figure out what leagues are best to upload, for the best balance of realism/computer speed.  I want my next save to be managing Everton.  So I don't necessarily have to load the Argentinian/Brazilian leagues but if you don't, then weird things have happened to me in previous saves where terrific players from these countries pop-up around the age of 20-21 while only having existed within the game for two/three seasons.  But at the same time those leagues are about an extra 5k-10k players to upload.  Maybe I should sacrifice a few of the leagues in Europe, like Belgium, Greece, and Ukraine?  What do you usually do?   And how big of a difference does it make in game speed if you have an estimated game speed of 2 1/2 stars vs 1 1/2?
