I've noticed recently that 4-3N-3 tends to do well against 4-5-1 V, Was playing a similar quality team on the 35T league recently and it was 0-0 at HT when I was playing 4-1-3W-2 and suddenly switched to 4-3N-3 and ended up winning 4-1. So maybe 4-3N-3 is definately worth a try, You 2 guys in that situation (SoMBrA and Zabanya) should look at the Semi-Final in a way they have absolutely nothing to lose because you are likely to lose the Semi-Final anyways but just go in and give it your "best shot".

Your 4-3N-3 orders would be long balls through the middle.
