I had already ben playing for about a weak and had done some of the things is said not to do, (I put some SP into my SA's at at very early levels and, not exactly knowing how they affected me) http://goallineblitz.com/game/player.pl?player_id=2136621

I gues my question is, at what time could my WR start worrying about SA's

could with minimal ALG loss? lvl 38
should? like lvl 55.
