Good work! You can see that 4-5-1V and 3-5-2V should work on ND because they can attack the flanks and are shaped to fit ND almost like an egg cup is for an egg. The only thing I would say, is that if you find yourself choosing between 3-5-2V and 4-5-1V, then look at the number of his strikers - if he has 1 then 3-5-2V. 2 strikers then either could work - depends on how good they are compared to your defenders. If he has 3 then you will want 4 defenders.
