Tomorrow in my cup game I face an opponent who plays a 4-3N-2-1 and I wanna counter his tactic with a 3N-2W(DML/DMR)-3N-2.

My problem is that today my best MC just got injured and my options are playing with a 2*MC or a 5* DMC as a MC, what player do u think will be better in that spot?

Another question is what arrows I need to put to my players assuming that I need to win the game (first game was a 2-2 draw in my home)

Thank you for your answers and sorry for my bad english.
