3-4-1-2 asymmetrical formation

[mr_niceguy]

Hi.my next opponent will be playing like this: dr, dc, dc - mc, mc, mc, ml - amc - st, st

I usually play 4-5v-1 (both flanks, short, normal).
Any ideas? Should i keep that formation and tactic or should i switch to 4-1-2-1-2 narrow diamond and play through the middle?
