If you can fit it, another vote for a center M3 mounted vertically, either tweeter-up below the screen or tweeter-down above the screen.
I started with M60 mains + VP100 center but but upgraded to a VP180 the day it was announced and as you might guess I am extremely happy with it. There is also a refurb VP160 in Axiom's deals section but you need to keep watching those pages in the hope that something comes up with the finish you want.
M60ti, VP180, QS8, M2ti, EP500, PC-Plus 20-39
M5HP, M40ti, Sierra-1
LFR1100 active, ADA1500-4 and -8
