Supreme Command Detachment - 3 GMNDK?

[Riddlesworth]

So ive been playing around with ways not to take power armour in my GK lists - strike squads and interceptors are great but i prefer the looks of terminators and dreadknights.

 

Obviously with limited nodel selection means duplicates. General consensus is that 2 gmndk, voldus and 3 strkke is the core competitive battalion, but is anyone running 3 gmndk? Using storm ravens to add volume of fire and paladins in a vanguard detachment to add some scoring prowess
