3n-1-3w-2n-1 could work, but if he's using force-counter tactics your MC and DMC will become overwhelmed. Basically your ML/MR will have to cover his DML/DMR, your MC and DMC will have to cover his AMC and 2 MCs (2:3 player ratio). When they break through you will have your 3 DCs and a scrambling DMC having to cover his 2MCs, AMC, and 2 ST (4:5 player ratio). Basically you might score some goals, but he will counter-attack, and if you don't score on an attacking drive, he will still counter-attack.
