Dismounted Gothic and Imperial Knights. Stats looked a little bit suspect at first, but they've been ferocious in battle. Last seige my DGK killed 100+ men and lost 10.

Any of the mounted knights. I've got Feudal Knights spread well throughout my empire now and they turn the tide of battle every time. Last battle my valour 3 FKs wiped out a full unit of Urban Militia in one charge.
