How do I beat 5-1-2-2?

Hey guys!

I tried googling this but couldnt find any decent answers so I'll try to post it here.

My opponent is using a 5-1-2-2 formation. How do I beat this formation?


---ST-ST---
---MC-MC---
----DMC----
LD-DC-DC-DC-RD

Thanks!

Im thinking about 3-5-2 V-formation, but how should I put my arrows and what tactics should I use?
