Thanks Sid, was actually thinking of going that route instead of the usual 9 player lineup. Will try it and hope the GE cooperates - I mean i tried playing 6 guys in a scrimmage and still my trainee was subbed out (stamina was 5 btw).
Unfortunately I played 5 guys last scrimmage and since the GE couldnt sub out my SF Trainee, it gave him a 2 week injury after 39 minutes :P
