I don't use offside trap as no-one can say what effect that really has on team performance. Similarly with 'hard defence', I use that only rarely - in fact the Palace Terriers Semi-Final 2nd Leg this season (3-0 up from home Leg against opponent +1 Level, +1.8 AQ, result was 1-0 for 4-0 aggregate) was the first time I've used it for either of my 'Palace' teams for two seasons.

So for either of these I can't advise either way...
